Wha's cDNA is and what is it good for?

[Winter]

cDNA stands for complementary DNA. It's a portion of DNA that indicates a protein and is produced from mRNA through reverse transcription. Its name is derived from the fact that it's sequence is complementary to the original mRNA.

- Single stranded cDNA is often used as a probe in physical mapping. It is also used to clone eukaryotic genes in prokaryotes.

- Double-stranded cDNA contains both the original sequence and it's complement.

- A cDNA library represents all the expressed DNA in a cell.

hope this helps
