check? What happens during telophase II? (Choose all that apply.) Chromosomes uncoil to form chromatin. Four haploid gametes are being formed. <<< Each newly forming cell gets a nucleus.<<

During telophase II, the fourth step of meiosis II, the chromosomes reach opposite poles, cytokinesis occurs, the two cells produced by meiosis I divide to form four haploid daughter cells, and nuclear envelopes [form].
Quote:
During telophase, chromosomes arrive at opposite poles and unwind into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears. Cytokinesis is the actual splitting of the cell membrane; animal cells pinch apart, while plant cells form a cell plate that becomes the new cell wall.

I think you might be missing something (don't take my word on this though)

iosangel:

Yea I think its a and c

iosangel:

not sure tho

kittybasil:

I might not be right don't medal me yet 😅😂

iosangel:

You still helped tho

kittybasil:

💀 Lol fine

justjm:

Option A, which is Chromosomes folding out into chromatin, is incorrect. That happens during DNA replication. DNA is emcased in a protein called Histone, several of which form a nucleosome. Several nucleosomes coil up to form Chromatin, which eventually forms the chromosome. Chromatin condensation occurs before cell reproduction and during G2/S of the interphase to allow the DNA replication. This happens via DNA methylation, which breaks down the histones. B and C is correct.
