Answer: Metaphase
How many chromatids are in a chromosome?

A chromatid (Greek khrōmat- ‘color’ + -id) is one half of a duplicated chromosome. Before replication one chromosome is composed of one DNA molecule. Following replication each chromosome is composed of two DNA molecules; in other words DNA replicationitself increases the amount of DNA but does not (yet) increase the number of chromosomes. The two identical copies—each forming one half of the replicated chromosome—are called chromatids. During the later stages of cell di…

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which aided by chaperone proteins bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division(wh…

The chromatids are joined at the centromere. There are 46 chromosomes in a human 23 pairs. Everyone has a set of chromosomes from their father and a matching set from their mother. They include a pair of sex chromosomes . The mother’s eggs always contain an X chromosome while the father’s sperm contains either a Y chromosome or an X chromosome …
