What is BIOTECHNOGY ?Biology+Technology
Involves the exploitation of biological agents or their components for generating useful products/services
The use of living microorganisms in systems or processes for the manufacture of the useful products , it may be algae, fungi, yeast bacteria ,viruses , cells of higher plants and animals or their subsystems or isolated components from living matter
- It consists of scaling up of biological processes

BIOSENSORSBiosensor technology couples our knowledge of
biology with advances in microelectronicsA biosensor is composed of a biological
component,such as cell, enzyme,or antibody, linked or tiny transducer.
HELPFUL IN1- Measuring nutritional value, freshness & safty of
food2-Locate & measure the environmental pollution3-Detect & quantify explosive, toxins and
biowarfare agents

RECOMBINANT DNA TECHNOLOGY 1- Recombinant DNA technology, joining together of DNA
molecules from two different species that are inserted into a host organism to produce new genetic combinations those are of value to science, medicine, agriculture, and industry.
2- Since the focus of all genetics is the gene, the fundamental goal of laboratory geneticists is to isolate, characterize, and to manipulate genes

The Inner Cell Mass is the Source of Embryonic Stem Cells
The embryo is destroyed by separating it into individual cells for the collection of ICM cells.
![Page 17: Scope of Biotechnology by Rajesh sahu](https://reader033.vdocuments.mx/reader033/viewer/2022061618/556c8ad3d8b42a7a738b48e5/html5/thumbnails/17.jpg)
A Site With Three Alleles Useful for DNA Fingerprinting
DNA fragments of different size will be produced by a restriction enzyme that cuts at the points shown by the arrows.
![Page 18: Scope of Biotechnology by Rajesh sahu](https://reader033.vdocuments.mx/reader033/viewer/2022061618/556c8ad3d8b42a7a738b48e5/html5/thumbnails/18.jpg)
DNA Fingerprinting Basics
If DNA is cut with a restriction enzyme that recognizes sites on either side of the region that varies, DNA fragments of different sizes will be produced.
A DNA fingerprint is made by analyzing the sizes of DNA fragments produced from a number of different sites in the genome that vary in length.
The more common the length variation at a particular site and the greater the number the sites analyzed, the more informative the fingerprint.
![Page 19: Scope of Biotechnology by Rajesh sahu](https://reader033.vdocuments.mx/reader033/viewer/2022061618/556c8ad3d8b42a7a738b48e5/html5/thumbnails/19.jpg)
NANO-BIOTECHNOLOGYNanobiotechnology is a new technology that works
at the scale of a single molecule or about a thousandth of a micron. It is the study and manufacture of super‐small structures and tiny machines made on the molecular scale.
These can be used to build structures that might be used in microchips for super‐fast computers made of DNA rather than silicon.
Nano biotechnology could be used to miniaturize sensors and improve drug delivery
![Page 20: Scope of Biotechnology by Rajesh sahu](https://reader033.vdocuments.mx/reader033/viewer/2022061618/556c8ad3d8b42a7a738b48e5/html5/thumbnails/20.jpg)
BIOTECHNOLOGY – DIOGNOSTIC Help diagnose prostate cancer or cholera or high cholesterol
Determine if women have a predisposition to breast cancer
Ensure that our blood supply is safe and doesn’t carry diseases from blood donors, such as HIV or mad cow disease and find out if a baby in the womb have issues like Down syndrome or spina bifida
Biotechnology is allowing us to diagnose disease earlier in the disease process, which greatly improves patient’ s prognosis
![Page 21: Scope of Biotechnology by Rajesh sahu](https://reader033.vdocuments.mx/reader033/viewer/2022061618/556c8ad3d8b42a7a738b48e5/html5/thumbnails/21.jpg)
PROTEIN ENGINEERINGProtein engineering is used often in conjuction
with recombinant DNA technology to improve existing proteins, such as enzymes, cell receptor,antibodies.
These proteins may be used in drug devlopment, food processing, industrial devlopment
![Page 22: Scope of Biotechnology by Rajesh sahu](https://reader033.vdocuments.mx/reader033/viewer/2022061618/556c8ad3d8b42a7a738b48e5/html5/thumbnails/22.jpg)
MONOCLONAL ANTIBODYMonoclonal antibody technology allows us to produce large
amounts of pure antibodies in the following way: We can obtain cells that produce antibodies naturally; we also have available a class of cells that can grow continually in cell culture. If we form a hybrid that combines the characteristic of "immortality" with the ability to produce the desired substance, we would have, in effect, a factory to produce antibodies that worked around the clock.
In monoclonal antibody technology, tumor cells that can replicate endlessly are fused with mammalian cells that produce an antibody. The result of this cell fusion is a "hybridoma," which will continually produce antibodies. These antibodies are called monoclonal because they come from only one type of cell.

FOOD PRODUCTION & PROCESSINGAgriculture companies are also using biotechnology to
improve production of meat and dairy products and to improve processing of other foods. Examples include:
Using Bovine somato‐tropin (BST), a hormone that helps to increase milk production.
Cloning cows that are high milk producers or beef stock. Reducing soy sauce fermentation from a few months to a few
days.Improving the processing of cheese, cocoa and tea. Using industrial enzymes to process corn syrup to high
fructose corn syrup which is used in many food products such as sodas, sauces, salad dressings tomato paste and ketchup.
Developing preservatives to replace sulfur and nitrates.Developing healthier vegetable oils with reduced saturated fats

HUMAN HEALTHThe biotechnology pharmaceutical industry has
grown immensely in the past 25 years.The first drug produced through biotechnology,
human insulin, has been helping to save lives since 1982. Since then, the biotechnology industry has brought to market more than 200 new drugs and vaccines that treat and prevent diseases. More than 400 new biotechnology drugs are in the process of being tested to see if they can be brought to market.

The Biotechnology of Reproductive Cloning
Even under the best of circumstances, the current technology of cloning is very inefficient.
Cloning provides the most direct demonstration that all cells of an individual share a common genetic blueprint.
