Answer:
A. Helicases
B. Single strand binding proteins
C. Single strand binding protein
D. Topoisomerases
Explanation:
The helicases bind on the replication fork aiding in the unwounding of the DNA helix to allow for replication. The single strange binding proteins attach/bind to the separated single stranded DNA after the replication fork to prevent re-annealing of the single stranded DNA preventing Hydrogen bond formation that reanneals these two strands together. The topoisomerases are found just ahead of the replication fork preventing overwounding/ positive supercoils of the DNA. They do this by introducing breaks into the phosphate backbone of the DNA allowing them rotate forming negative supercoils and attaching the breaks once the DNA strand is relaxed.

Explanation: srry if I'm wrong
The bonds between amino acids are PEPTIDE chemical bonds (Option B).
<h3>What is a peptide bond?</h3>
A peptide bond is a special type of chemical bond between adjacent amino acids in a polypeptide chain.
Peptide bonds are known to be formed by a chemical process called dehydration synthesis.
In conclusion, amino acids bind by PEPTIDE chemical bonds (Option B).
