Biology Question on Applications of Biotechnology
Which one of the following is not a process of DNA recombinant technology?
A
Isolation of DNA
B
RNA interference (RNAi)
C
Introduction of Restriction endonucleases
D
Culturing the host cells in a medium at a large scale
Answer
RNA interference (RNAi)
Explanation
Solution
RNA interference (RNAi) is a biological process where RNA molecules inhibit gene expression or translation by neutralizing targeted mRNA molecules. This is not a standard part of recombinant DNA technology, which typically involves isolating DNA, using restriction enzymes, and culturing modified cells.
