Which of the following occurs just before the cell enters the G2 stage of the cell cycle? *
O The nuclear membrane disintegrates.
O DNA replicates
O Centrioles form
O The nucleolus divides

DNA replicates

Explanation:

S phase (Synthesis Phase) During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids, the synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration

youre right there are

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
