​Transcription

updated: October 5, 2022

Definition

Transcription, as related to genomics, is the process of making an RNA copy of a gene’s DNA sequence. This copy, called messenger RNA (mRNA), carries the gene’s protein information encoded in DNA. In humans and other complex organisms, mRNA moves from the cell nucleus to the cell cytoplasm (watery interior), where it is used for synthesizing the encoded protein.

Narration

Transcription. Transcription is like translating a book from one language to another. While DNA is more stable of a molecule, RNA is the more universal biological language.
