retrogene
(noun)
a DNA gene copied back from RNA by reverse transcription
Examples of retrogene in the following topics:
-
Gene Duplications and Divergence
- If viral proteins attach irregularly to cellular mRNA, they can reverse-transcribe copies of genes to create retrogenes.
- Retrogenes usually lack intronic sequence and often contain poly A sequences that are also integrated into the genome.
- Many retrogenes display changes in gene regulation in comparison to their parental gene sequences, which sometimes results in novel functions.
