Answer:

Rbosomes contain three binding sites: the A site, the P site, and the E site

Explanation:

1. Protein synthesis occurs with the combination of ribosomes (large subunit and small subunit) mRNA and tRNA.

2. mRNA contains nucleotide sequences in the form off codons, which codes specific amino acids according to their bases.

3. tRNA contains anti-codons, and according to the codons in mRNA, tRNA brings amino acids to the ribosomes and the synthesis of protein occurs.

4. Ribosome has three binding sites: The A site, the P site, and the E site. First of all, an aminoacy-tRNAs (a tRNA containing amino acid covalently attached) first enter the ribosome at the A site, and then to P site and finally exits via E site.
