Biotechnology and Genetic engineering
Dr. Abeer Fauzi Murad Lecture(1)a

What is the biotechnology?
Biotechnology, as the word suggests, is combination of biology and technology. Biotechnology is the use of technology to use, modify or upgrade the part or whole of biological system for industrial and human welfare.
Biotechnology:- using living organisms, or the products of living organisms, to create pharmaceutical, diagnostical, agricultural, environmental and other products to benefit society or solve a problem.
The science Biotechnology used to alter genetic information in animals and plants to improve them in some way that benefit peoples and using scientific methods with organisms to produce new products or new forms of organisms.
Biotechnology:- any technique that uses living organisms or substances from those organisms to make or modify a product, to improve plants or animals, or to develop microorganisms for specific uses.
Biotechnology: the branch of molecular biology that studies the use of microorganisms to perform specific industrial processes; "biotechnology produced genetically altered bacteria that solved the problem.
Break biotechnology in to it?s root words : bio= the use of biological processes ; technology= to solve problems or make useful products.
Biotechnology is defined as:
1- “Biotechnology is the application of biological organisms, system or
process to manufacturing and service industries." (British or processes to manufacturing and Biotechnologist)
2-“Biotechnology is the integrated use of biochemistry, microbiology, and engineering sciences in order to achieve technological (industrial) application of the capabilities of microorganisms, cultured tissue cells.” (European Federation of Biotechnology)
3-“Biotechnology is the controlled use of biological agents, such as microorganisms or cellular components.” (US National Science
Foundation)
The goals of biotechnology:
1-To understand more about the processes of inheritance and gene expression
2-To provide better understanding and treatment of various diseases, particularly genetic disorders
3-To generate economic benefits, including improved plants and animals for agriculture and efficient production of valuable biological molecules
Example: Vitamin A fortified engineered rice
Which branches are involved in biotechnology: Microbiology, Genetics, Biochemistry, Biophysics, Molecular Biology, Bioengineering, etc.
As say before Biotechnology is the use of living things especially cells and bacteria for production of various products for benefiting human beings. It is a combination of various technologies, applied together to living cells, including not only biology, but also subjects like mathematics, physics, chemistry and engineering. Its application ranges from agriculture (Animal Husbandry, Cropping system, Soil science and Soil Conservation, Plant Physiology, Seed Technology etc and Crop Management) to industry (food, pharmaceutical, chemical, byproducts, etc.), medicine, nutrition, environmental conservation, Cell Biology, making it one of the fastest growing fields. Biotechnology is to modify genetic structure in animals and plants to improve them in desired way for getting beneficial products.
History of biotechnology:
People were using biotechnology techniques thousands years before but they did not named their working field as biotechnology. The name biotechnology was given by Hungarian engineer Karoly Ereky in 1919 to describe a technology based on converting raw materials into a more useful product.
Stages of Biotech:
1-Ancient
1-Begins with early civilization
2-Developments in agricultural and food production
Few records exist
3-The ancient Egyptians made wine using fermentation techniques based on an understanding of the microbiological processes that occur in the absence of oxygen.
4-Egyptians also applied fermentation technologies to make dough rise during bread making. Due in part to this application, there were more than 50 varieties of bread in Egypt more than4,000 years ago
5-In wetter parts of the Nile Valley, Egyptians also bred geese and cattle to meet their society s nutritional and dietary needs.
6- Yogurt was made at homes but the reason of the conversion of milk into yogurt was unknown to old people. Later researches showed that yogurt is made due to the action of yeast added to milk; which is also biotechnology as it uses a microorganism for benefiting human.
7- People have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics. For example, this technique was used with corn to produce the largest and sweetest crops.
2-Classical
1-Follows ancient
2-Makes wide spread use of methods from ancient, especially fermentation
3-Methods adapted to industrial production
4-Produce large quantities of food products and other materials in short amount of time
5-Meet demands of increasing population
6-Many methods developed through classical biotech are widely used today.
3-Modern
The Second World War became a major impediment in scientific discoveries. After the end of the second world war some, very crucial discoveries were reported, which paved the path for modern biotechnology and to its current status.
1-in 1953, JD Watson and FHC Crick for the first time cleared the mysteries around the DNA as a genetic material, by giving a structural model of DNA, popularly known
as, ‘Double Helix Model of DNA’. This model was able to explain various phenomena related to DNA replication, and its role in inheritance
2- Dr. Hargobind Khorana was able to synthesize the DNA in test tube, while Karl Mullis added value to Khorana s discovery by amplifying DNA in a test tube, thousand times more than the original amount of DNA.
3- Using this technological advancement, other scientists were able to insert a foreign DNA into another host and were even able to monitor the transfer of a foreign DNA into the next generation.
4- In 1997, Ian Wilmut an Irish scientist, was successful to clone a
Sheep and named the cloned sheep as ‘Dolly’
5- In 2003, the Human Genome Project completes sequencing of the human genome
6- In 1978, Boyer was able to isolate a gene for insulin (a hormone to regulate blood sugar levels) from human genome using biotechnology. He then inserted it into bacteria, which allowed the gene to reproduce a larger quantity of insulin for diabetics.
Modern biotechnology provides breakthrough products and technologies to combat rare diseases, reduce our environmental footprint, feed the hungry, and use less and cleaner energy, and have safer, cleaner and more efficient industrial manufacturing processes. Currently, there are:
*More than 250 biotechnology health care products and vaccines available to patients, many for previously untreatable diseases.
*More than 13.3 million farmers around the world use agricultural biotechnology to increase yields, prevent damage from pests and reduce farming s impact on the
Environment.
*More than 50 bio refineries are being built across North America to test and refine technologies to produce biofuels and chemicals from renewable biomass, which can help reduce greenhouse gas emissions.
Fields in biotechnology
Famous biotechnological fields are:
(1) Genetic engineering

Genetic engineering, also called genetic modification, is the direct manipulation of an organism s genome using biotechnology. Genes are the chemical blueprints that determine an organism s traits. Moving genes from one organism to another transfers those traits. Through genetic engineering, organisms can be given targeted combinations of new genes, and therefore new combinations of traits that do not occur in nature and, indeed, cannot be developed by natural means. Such an approach is different from classical plant and animal breeding, which operates through selection across many generations for traits of interest.
*-manipulation of genes is called genetic engineering or recombinant DNA technology
*-genetic engineering involves taking one or more genes from a location in one organism and either
*- Transferring them to another organism
*- Putting them back into the original organism in different combinations
(2) Tissue culture
Tissue culture, a method of biological research in which fragments of tissue from an animal or plant are transferred to an artificial environment in which they can continue to survive and function. The cultured tissue may consist of a single cell, a population of cells, or a whole or part of an organ. Cells in culture may multiply; change size, form, or function; exhibit specialized activity(muscle cells, for example, may contract); or interact with other cells.
(3) Cloning
Cloning describes the processes used to create an exact genetic replica
of another cell, tissue or organism. The copied material, which has the same genetic makeup as the original, is referred to as a clone. The most famous clone was a Scottish sheep named Dolly. There are three different types of cloning:
*Gene cloning, which creates copies of genes or segments of DNA
*Reproductive cloning, which creates copies of whole animals
*Therapeutic cloning, which creates embryonic stem cells. Researchers hope to use these cells to grow healthy tissue to replace injured or tissues in the human body diseased.
General Categories of biotechnology
• Medical Biotechnology-Vaccines, diagnostics, pharmaceuticals
• Industrial Biotechnology - Enzymes and microorganisms for processing products
• Environmental Biotechnology Microorganisms for bioremediation
• Agricultural Biotechnology - Enhanced crops, feed and fertilizers
Branches Of Biotechnology
Biotechnology has more than a few different branches which are referred to by dissimilar terms mainly noticeable with dissimilar colors to clarify the biotechnological field that it is used in. The majority extensively used ones will be introduced here. First of all there is the red biotechnology that is used for medical processes, like finding genetic cures by going through genomic manipulations and creating organisms to produce antibiotics. There are several branches of Biotechnology. They are classified as:
A) Blue Biotechnology:
This branch of biotechnology helps to control the marine organisms and water borne organisms. It is a process which has to do with marine or underwater environment. The use of this biotechnology is very rare. Blue biotechnology is used to protect the marine organisms from harmful diseases underwater.
B) Bioinformatics:
Bioinformatics is the combination of computer and biotechnology. It helps in finding the analysis of data’s related to Biotechnology. It is used for various purposes like drugs, for the development of medicines; it is also used to improve the fertility of crops and plants and also for pest, drought and it is resistance to diseases. Bioinformatics is known and referred by the term computational biology. It plays an important and a vital role in areas like Functional genomics, structural genomics and proteomics these areas contribute a lot and become a key contributor to Biotechnology and pharma sector.
C) Green Biotechnology:
Green Biotechnology is the term used for the agricultural sector. With the help of the process called the Micro propagation (a practice of producing larger number of plants through the existing stock of plants) which helps in selecting the right quality of plants and crops. Also with the help of Transgenic plants (plants whose DNA is modified); this design of transgenic plants helps to grow in a specified environment with the help of certain chemicals.
D) Red Biotechnology:
Red biotechnology is referred to as Medical Biotechnology. It is used for the production of drugs and antibiotic medicines. It also helps to create or design organisms. Through the process of genetic manipulation it helps to cure genetic issues in organisms. It also helps in analyzing diseases in organisms. It also helps in developing new ways of diagnosis by performing tests. With the help of stem cell therapy, it helps the organs to grow and it also cures the damaged issues in organisms.
E) White Biotechnology:
White Biotechnology is also called and known by the name Industry Biotechnology. This kind of biotechnology is used and applied in industries and its processes. The various uses of this Biotechnology includes; biopolymers (Plastics) Substitutes, new invention of vehicle parts and fuels for the vehicles, invention of fibers for the clothing industry, it is also involved in developing new chemicals and the production process.
