Question

Consider a cell in which one of the proteins or enzymes involved in dna replication is altered in a way that results in an increased rate of single-base changes in the newly synthesized dna strand. which function of which protein is most likely disrupted in this situation?

Answer 1

Increased rate of single-base changes in the newly synthesized DNA strand may be due to the MUTATION IN THE PROOF-READING ACTIVITY OF DNA POLYMERASE ENZYME.

DNA polymerase enzyme is responsible for adding the nucleotides complementary to the old strand. It is a very specific enzyme that works with precision. It has a proof reading activity that allows correct addition of nucleotides.
