Hello, I figured your question was somewhat incomplete so I went online to search for it and here is what I found:
A cell containing 92 chromatids at metaphase of mitosis would, at its completion, produce two nuclei each containing how many chromosomes?
a. 12
b. 16
c. 23
d. 46
e. 92
Answer:
The correct answer is: d) 46.
Step-by-step explanation:
Before DNA replication, each chromosome in the cell has only 1 chromatid. When DNA replication occurs, the chromatids are duplicated, which makes each chromosome have 2 chromatids. This is an important preparation for Mitosis, in which the cell will divide into two and each chromatid will go to each cell.
Metaphase is one of the phases of Mitosis. In Metaphase, the chromosomes -which have two chromatids each- line up in the middle of the cell, at its equator. In the next phase, Anaphase, the 92 chromatids that were lined up in the middle will be pulled to opposite sides: 46 chromatids will go to one pole, and the other 46 chromatids will go to the other pole. After a few processes more, the two new cells will have 46 chromosomes each, with only one chromatid per chromosome.
