The answer to your question is A
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.
<span>Only 10% of patients taking this type of medication experiences what we call self - limited post injection reactions, and the signs and symtoms felt by the patient are just merely the side effects. it will usually last from15 to 20 minutes. there is no necessary treatment requires, perhaps the nurse should just stay with the patient inorder to decrease the anxiety accompanied by this typeof reaction. Cardiorespiratory support is not recommended for this is not a cardiotoxic reaction.</span>
