Question

In anaphase,

A.Sister Chromatids move toward the poles of the cell

B.Homologous chromosome move toward the poles of the cell

C.Homologous chromosome line up along the metaphase plate

D.Sister Chromatids line up along the metaphase plate

Answer 1

Option- A is correct- Sister chromatids move toward the poles of the cell.

Anaphase takes place in both meiosis and mitosis. In meiosis, Anaphase 1 and 2 take place. In Anaphase 1, homologous chromosome moves toward the poles of the cell, and in Anaphase 2, centromere divides and sister chromatids move toward the poles of the daughter cell.

In mitosis, only Anaphase 2 of meiosis takes place, which means centromere divides and sister chromatids move toward the poles of the daughter cell.

Therefore, the more correct answer is Option-A.

Option-C- Homologous chromosome line up along the metaphase plate in the metaphase stage of mitosis not in an anaphase stage.

D- No such stage takes place in cell division. Either chromosome line up along the metaphase plate (mitosis and meiosis 2) or pair of chromosomes (meiosis 1)
