7.3 Translation (AHL)

Essential Idea:
Information transferred from DNA to mRNA
is translated into an amino acid sequence

Aims:

Initiation of translation involves assembly of the components that carry out the process
Synthesis of the polypeptide involves a repeated cycle of events
Disassembly of the components follows termination of translation
Free ribosomes synthesise proteins for use primarily within the cell
Bound ribosomes synthesise proteins primarily for secretion or for use in lysosomes
Translation can occur immediately after transcription in prokaryotes due to the absence of a nuclear membrane
