initiation first step of the translation process, when a ribosome assembles at the AUG start codon on mRNA
mRNA formed by transcription; carries DNA's message from the nucleus to the cytoplasm
promoter specific DNA region where RNA polymerase begins opening up the double helix
RNA polymerase enzyme involved in transcription
