Summary Introduction
To review:
Production of rDNA (recombinant deoxyribonucleic acid) drug Humulin.
Introduction:
Insulin is a big requirement for people suffering from insulin-dependent diabetes (diabetes mellitus). Earlier, insulin from pigs and cattle was used for the therapy of these patients. This was not only expensive and difficult to extract, but also raised a lot of ethical questions. Being from a nonhuman source, there would also be a risk of an immune response against it. RDT or recombinant DNA technology has changed the world of research. Proteins produced as a result of RDT can be used as drugs.

In the DNA of what kind of cell must a mutation occur for the genetic change to be passed down to future generations?
Base analogs are mutagenic because of which characteristic?
a. They produce changes in DNA polymerase that cause it to malfunction.
b. They distort the structure of DNA.
c. They are similar in structure to the normal bases.
d. They chemically modify the normal bases.
the human immunodeficiency virus HIV uses RNA rather than DNA to encode genetic information. During infection, however, HIV uses an enzyme known as reverse transcriptase to generate double-stranded DNA. Generally speaking, how would the enzyme generate a double strand of DNA from a single strand of RNA?
