Question

**EDIT: i put the answer i thought was correct, i'm just not sure if it's right, which is why i posted the question.

Cloning eukaryotic genes in bacteria for protein production requires the removal of introns, which is done by producing copies from the mRNA using retrovirus reverse transcriptase. a hybridization Ob. MRNA c microarray Od DNA Ce library

Answer 1

Correct answer- (d) CDNA

The enzyme reverse transcriptase has both polymerising role as well as RNAse H role and functions to convert a single stranded mRNA molecule first to a single stranded DNA, then RNASe H activity of the enzyme reverse transcriptase degrades the mRNA strand. Now, utilizing the DNA strand as the template, second strand of DNA, complementary to the first one gets synthesized, thus producing a double stranded DNA or cDNA from mRNA.
