The opening of voltage-gated K+ channels is slower and more prolonged than the opening of the Na + channels, and much of the increase in K + conductance comes after the increase in Na+ conductance

Translesion synthesis is catalyzed by a specialized class of DNA polymerases that synthesize DNA directly across the site of the damage. In E. coli, DNA Pol IV (DinB) or DNA Pol V (a complex of the proteins UmuC and UmuD’) performs translesion synthesis.  DinB and UmuC are members of a distinct family of DNA polymerases found in many organisms known as the Y family of DNA 

polymerases. There are five translesion polymerases known in humans, four of which belong to the Y family.
