In nucleotide excision repair, damaged dna is excised by what enzyme(s)? in nucleotide excision repair, damaged dna is excised by what enzyme(s)? ligase nuclease dna polymerases primase helicase

The correct answer is helicase and nuclease.

Nucleotide excision repair is a mechanism for DNA repair which removes DNA damage often induced by ultraviolet light (UV). The mechanism includes recognition of damage, dual incision, repair, and ligation.

The step of incision occurs via enzyme which has helicase activity (unwind DNA and cut it). The same enzyme also has endonuclease activity (removal of a damage-containing DNA).

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
