Gene activity refers to the level of expression or production of a specific gene within an organism. It determines whether a gene is turned "on" or "off" and can impact the synthesis of proteins and other molecules.
Epigenetics involves modifications to DNA that can affect gene activity without changing the underlying DNA sequence.
Transcription: Transcription is the process where genetic information from DNA is copied into RNA molecules.
Translation: Translation is the process where RNA molecules are used by ribosomes to produce proteins.
