What processes occur during G2 phase? Choose all which apply. Cells do their normal work
Cells assess DNA replication
Cells duplicate their DNA
Cells synthesize proteins necessary for division
Cells divide their DNA into two nuclei

Explanation:

the last part of interphase is called the G2 phase. The cell has grown, DNA has been replicated, and now the cell is almost ready to divide. This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.
