Which happens first in the process of translation?
mRNA leaves the nucleus and enters the cytoplasm, where it attaches to a ribosome.
The ribosome reads the codon on the mRNA. A tRNA molecule with the complementary anticodon arrives and binds to the codon. The tRNA is also carrying it's amino acid.
The tRNA molecule then separates from the nucleus and leaves the ribosome.
The ribosome then moves along to the next codon and a new tRNA molecule takes it's place on the mRNA strand. The new amino acid brought in joins the other ones through a polypeptide bond.
Amino acids are added to the growing chain, called a polypeptide chain, until the ribosome reaches a stop codon. The polypeptide chain is then let go, and it folds into a protein molecule.
