Fact Checking (2/3)

Question 1

What is another name for Genetic Errors?

Answer 1

Base pair errors, they can occur but they are not frequent.

Question 2

How can the DNA polymerase tell if their is an error?

Answer 2

DNA polymerase proof reads its work after adding a nucleotide, if the complementary strand and the original strand doesn’t have a hydrogen bond in the middle, there is a mismatch.

Question 3

When there is a mismatch, how does it get fixed?

Answer 3

Nucleotide Excision Repair.

Question 4

Process of the Nucleotide Excision Repair

Answer 4

1.) Nucleases cut damaged DNA
2.) DNA polymerase corrects the base pairs
3.) DNA ligase seals the gaps.
