How would the cDNA created in a lab compare to the original DNA?
A)It would contain only the genes that were producing proteins in the cell at the time the cDNA was created.
B)It would be identical to the original DNA.
C)It would be a single strand instead of the original double-stranded DNA.
D)It would be circular, similar to bacterial DNA.

Question

Quizplus · Accepted Answer

cDNA is created by reverse transcriptase enzyme by using mRNA as a template. This cDNA molecule will have only the exonic regions and not the intronic regions (non-coding regions) of the original DNA. Therefore, it contains only the genes that were being transcribed in the cell at the time the mRNA was extracted, and not the entire genome.
