16 Questions
What is depurination?
The loss of purines from a nucleotide
How does depurination cause mutation?
By creating a deletion mutation
What type of nucleotides are lost during depurination?
Adenine or guanine
What enzyme recognizes and corrects depurinated sites?
DNA repair enzymes
What happens if a depurinated site is not corrected?
DNA polymerase will skip the depurinated site during replication
What type of mutation is created when a depurinated site is not corrected?
Deletion mutation
What happens to the depurinated nucleotide in successive replications?
It is eventually removed, creating a permanent deletion mutation in one copy
What type of hydrolysis reaction causes depurination?
Spontaneous hydrolysis reaction
