Question
DNA technology has changed the pharmaceutical Industry and medicine. Researchers use DNA technologies to produce drugs, diagnose diseases, and produce vaccines.
Step 1
One common method is recombinant DNA technology, where a gene of interest is inserted into a bacterial or yeast cell, allowing these cells to produce a protein that can be used as a drug. For example, insulin, used to treat diabetes, is commonly produced using Show more…

In recent years, DNA sequencing has become an important tool in biomedical science. What is the use of knowing the DNA sequence of genes from an individual? identifies proteins that are misregulated during disease provides a complete understanding of disease mechanisms influences treatment plans for certain drugs can provide information about the risk of developing specific diseases in the future
Assertion: Developing a DNA vaccine is a part of biotechnology. Reason: Biotechnology uses live organism or enzyme form organisms to produce products and processes useful to humans.
Bacterial transformation and bacteriophage labeling experiments proved that DNA was the hereditary material in bacteria and in DNA-containing viruses. Some viruses do not contain DNA but have RNA inside the phage particle. An example is the tobacco mosaic virus (TMV) that infects tobacco plants, causing lesions in the leaves. Two different variants of TMV exist that have different forms of a particular protein in the virus particle that can be distinguished. It is possible to reconstitute TMV in vitro (in the test tube) by mixing purified proteins and RNA. The reconstituted virus can then be used to infect the host plant cells and produce a new generation of viruses. Design an experiment to show that RNA, rather than protein, acts as the hereditary material in TMV.
