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).

During which period did humans first appear on Earth? Quaternary Neogene Paleogene Cenozoic
anyanavicka [17]

The answer is Neogene

Explanation:

It cannot be Cenozoic because that is an era. Not a period. Paleogene, Neogene, and Quaternary (our current period) are all periods within the Cenozoic Era (our current era). On the geologic time scale, there are Eras, Periods, and Epochs (and a few more classifications). Humans first appeared in the Miocene epoch which is an epoch in the Neogene period (in the Cenozoic era).

This is why the answer is Neogene.

Hope this helps...
