PROTEIN SYNTHESIS 2 parts

TRANSCRIPTION DNA sends instructions to ribosomes as mRNA

TRANSCRIPTION DNA sends instructions to ribosomes as mRNA RNA polyermase separates DNA strands

TRANSCRIPTION DNA sends instructions to ribosomes as mRNA RNA polyermase separates DNA strands One strand of DNA used as a template

TRANSCRIPTION DNA sends instructions to ribosomes as mRNA RNA polymerase separates DNA strands One strand of DNA used as a template Copy of mRNA is made

mRNA leaves the nucleus and travels to the ribosomes
