What is CDNA

Question

What is cDNA?
A) A DNA copy of an RNA molecule
B) A DNA molecule used for translation
C) A DNA molecule that has been spliced
D) An RNA molecule with cytosine instead of uracil

Accepted Answer

cDNA stands for complementary DNA, which is a DNA copy of an RNA molecule. This is made possible by the enzyme reverse transcriptase, which can synthesize DNA from an RNA template. The resulting cDNA can then be used for various research purposes, such as gene cloning or expression analysis.
