Q

There are …..amino acids that are created from …..codons

A

20 amino acids
64 codons
The reason that is because there is redundancy

Q

The steps for translation are:

A

Initiation: The AUG codon is recognized and met established as the first amino acid

Elongation: Amino acids are added 1 by 1 through trna transferring amino acids to the A site

Termination: The addition of amino acids stops and when the ribosomes encounter a stop codon
