Practice question
Question
Adenine can undergo a spontaneous change to hypoxanthine in a cell, leading to a DNA base pair mismatch. The CORRECT combination of enzymes that are involved in repairing this damage is
Explanation
Nuclease, DNA polymerase, DNA ligase is correct because it matches established biochemistry principles where nuclease, dna polymerase, dna ligase represents the functional mechanism. Alternatives such as Nuclease, DNA ligase, helicase, Primase, DNA polymerase, DNA ligase contradict experimental evidence and standard textbook descriptions.
