Which phase of the cell cycle does the cell spend most of its life?
Interphase
Location of transcription and translation
Transcription - eukaryotes: nucleus, prokaryotes: cytoplasm

Small localised region of DNA where the double helix unwinds during transcription
Transcription bubble
The original source of all genetic variation and how they occur
Mutation - inherited or environmental
