In a single chromosome, how many chromatids are present?
Understand the Problem
The question is asking about the number of chromatids present in a single chromosome. Chromatids are the two identical halves of a duplicated chromosome. In a single chromosome, there is typically one chromatid, but after DNA replication, each chromosome consists of two sister chromatids. The question implies a general biological concept that needs clarification on what stage of the cell cycle is being referred to.
Answer
One or two chromatids depending on the cell cycle stage.
A single chromosome can have one or two chromatids. Before cell division, a chromosome consists of one chromatid. After DNA replication, during cell division, a chromosome has two sister chromatids.
Answer for screen readers
A single chromosome can have one or two chromatids. Before cell division, a chromosome consists of one chromatid. After DNA replication, during cell division, a chromosome has two sister chromatids.
More Information
Chromatids form during DNA replication in preparation for cell division, ensuring each daughter cell receives a complete set of genetic information.
Tips
It is important to understand that the number of chromatids changes depending on whether the cell is in interphase or about to undergo mitotic or meiotic division.
