How many sister chromatids are in a cell?

How many chromatids are in G1?

In G1, each chromosome is a single chromatid. In G2, after DNA replication in S phase, as cell enter mitotic prophase, each chromosome consists of a pair of identical sister chromatids, where each chromatid contains a linear DNA molecule that is identical to the joined sister.

What is the metaphase 1?

Metaphase I is the second stage in meiosis I. … At metaphase I, the homologous chromosomes move to the center of the cell and orient themselves along an equatorial plane, forming the so-called metaphase plate.

What happens anaphase?

During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. … The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
