What is the amount of DNA in anaphase 1?

During anaphase, these paired homologous chromosomes are separated. During telophase-1 cytokinesis takes place and two daughter cells are made. So in anaphase-1, the cell has not yet divided and the DNA amount is the same as it was in prophase-1 that is ‘X’.

Is there DNA in anaphase?

The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere. During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.

How many molecules of DNA are found in a chromosome?

Before replication, one chromosome is composed of one DNA molecule. In replication, the DNA molecule is copied, and the two molecules are known as chromatids. During the later stages of cell division these chromatids separate longitudinally to become individual chromosomes.

Where are chromosomes located during anaphase?

Mitosis: In Summary

In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes.

Why is anaphase so short?

Anaphase is considered the shortest stage of the cell cycle because this stage involves only the separation of sister chromatids and their migration
