Question

Quizplus · Accepted Answer

A cDNA clone is a DNA molecule that is complementary to an mRNA molecule. This type of clone is created through reverse transcription, where the mRNA is used as a template to synthesize a complementary DNA strand. The resulting cDNA can then be cloned and used for various purposes, such as gene expression analysis.
