Q

What is the 1st stage of translation?

A

The mRNA attaches itself to a ribosome and tRNA molecules carry amino acids to it

ATP provides the energy needed for the bond between the amino acid and the tRNA molecule to form

Q

What is the 2nd stage of translation?

A

A tRNA molecule with an anticodon complementary to the 1st codon on mRNA attaches itself to the mRNA by complementary base pairing

A 2nd tRNA molecule attaches itself to the next codon on the mRNA the same way

Q

What is the 3rd stage of translation?

A

The 2 amino acids attached to the tRNA molecules are joined by a peptide bond

1st tRNA molecule moves away, leaving its amino acid behind

Q

What is the 4th stage of translation?

A

A 3rd tRNA molecule binds to the next codon on the mRNA. Its amino acid binds and the tRNA molecule moves away

This process continues, producing a chain of linked amino acids until there’s a stop signal on the mRNA molecule
