In prophase,ribosomal RNA synthesis stops when the chromosomes condense,and as a result:
A)the chromosomes lengthen.
B)the nuclear envelope reforms.
C)the nucleolus disappears.
D)the chromosomes line up at the equator of the cell.

Question

Quizplus · Accepted Answer

In prophase, the chromosomes condense and become visible under a microscope. This process is accompanied by the disappearance of the nucleolus, which is responsible for ribosomal RNA synthesis. Therefore, option C is the correct answer. The other options (A, B, D) are not accurate descriptions of what happens in prophase.
