1. Which of the following is not a homologous recombination pathway in Eukaryotes?

2. Flap endonucleases are associated with:

3. Cancer can be the ultimate result of:

4. Both prokaryotes and eukaryotes have a missense repair mechanism.

5. Which enzyme is not used in a DNA repair pathway?

Solution

1. Which of the following is not a pathway of homologous recombination in eukaryotes?

Ans. NBD is not a pathway of homologous recombination in eukaryotes.

2.Flap endonucleases are associated with

ans NER nucleotde excission repair

3. Cancer can be an ultimate result of

ans. e. All the options are correct

4. both prokaryotes and eukaryotes have missense repair mechanism.

Ans. a true

explanation: It is very necessary for both prokaryotes ans eukaryotes to to recognize the mismatched base pairs and excise the incorrect the base and carry out the repair synthesis. the genetic stability requires not only an extremely accurate mechanism for replicating DNA but also mechanisms for repairing it.

5. Which enzyme is not in a DNA repair pathway?

Ans. c Glutathione S- transferase.

Explanation. The enzyme Glutathione S transferase is an enzyme known for its ability to catalyze the conjugation of the reduced form of glutathione to xenobiotic substrates for the purpose of detoxification which is nit a mechanism involved in DNA repair.
