Select the correct sequence:

• B, C, E, D, A

• A, B, C, D, E

• B, A, C, E, D

• A, D, E, C, B

True or false:

The chromosomes of prokaryotes attach to the cell membrane during binary fission.

• True

• False

Which state indicates DNA replication?

• A-B

• B-C

• C-D

• D-E

Does the actual number of chromosomes change in the process of DNA replication?

Note: think about whether chromosomes are still attached after DNA replication

• Yes it increases

• Yes it decreases

• No it stays the same

What is happening in section D-E?

Plant cells are unable to pinch-off during cytokenesis, unlike animal cells. In your own words, briefly explain the process that occurs in plant cell cytokinesis that separates the two daughter cells from each other.
