Question

Which of the following is true about the accuracy of DNA replication? A: Many errors are made during DNA replication, but this does not matter because of the immense size of the DNA molecule. B: Many errors are made during DNA replication, but this does not matter because repair enzymes will mend the errors. C: The few errors made by DNA polymerase are usually corrected by repair enzymes. D: DNA polymerase makes very few errors, so no repair enzymes are needed. E: DNA polymerase always makes a perfect copy of the original DNA.

Answer 1

C. The few errors made by DNA polymerase are usually corrected by repair enzymes.

Explanation:

DNA replication is a very important process, as the daughter cells will need the same DNA as the parent. DNA replication makes this happen.

During DNA replication, some errors may occur. While these errors are few and far between, they still do happen. If a lot of errors occur, this could result in the damage of DNA.

Repair enzymes, such as DNA ligase, help repair the errors in the DNA so everything goes smoothly. Repair enzymes fix the DNA so no genetic information is lost.
