The DNA which is synthesized from mRNA by reverse transcriptase are called:
Correct answer: C. cDNA
- A. Endonucleases
- B. Plasmids
- C. cDNA
- D. None of the above
Explanation
This involves converting the RNA back into a DNA copy, known as complementary DNA (cDNA) by reverse transcriptase. Thus, when amplifying eukaryotic genes by PCR the cDNA version is often used (rather than the true chromosomal gene sequence) since this lacks the introns.
