the site in the ribosome where a peptide bond forms with previously deposited amino acids is called the
p site.
a site.
e site.
initiation site.

Explanation:

• During translation, adjacent amino acids form peptide bonds. Peptide bonds are covalent bonds that link amino acids together to form a polypeptide chain. Tertiary structure refers to the three - dimensional folding of a protein, hydrogen bonds are weaker bonds (e.g., in DNA base - pairing or protein secondary structure), and thymine dimers are a type of DNA damage.
• In the ribosome, the P site (peptidyl - tRNA site) is where a peptide bond forms with previously deposited amino acids. The A site (aminoacyl - tRNA site) is where the incoming aminoacyl - tRNA binds, the E site (exit site) is where the tRNA exits after it has donated its amino acid, and the initiation site is more related to the start of translation rather than the specific site for peptide bond formation with previously deposited amino acids.

Answer:

• First question: C. peptide bonds
• Second question: A. P site
