5-bromouracil induces transitions in both directions, A:T ↔ G:C Deamination of adenine results in A:T → G:C transitions and the deamination of cytosine produces G:C → A:T transitions, so nitrous acid induces transitions in both directions

The average number of nucleotides added before a polymerase dissociates defines its processivity. Nucleotides added per unit time dissociates defines its polymerisation

The 3’->5’ exonuclease activity removes the mispaired nucleotide, and the polymerase begins again known as proofreading
