codon that signals the start of translation

Where does translation take place?

cytoplasm

Define Translation

decoding of an mRNA message into a polypeptide chain

Define Genetic Code

instructions contained in a gene that tells it how to make a specific protein

Amino acids are coded by...

mRNA base sequences
