Types of Chromatid
There are two types of chromatids, based on their position during cell division:
- Sister Chromatids are two identical copies of a single chromosome, which are held together by a centromere. Sister chromatids are formed during DNA replication and separate from each other during cell division.
- Homologous Chromatids – These are two chromatids that belong to homologous chromosomes, which carry similar genetic information. Homologous chromatids are involved in meiosis, a specialized form of cell division that leads to the production of gametes.
Chromatid
Chromatids are one of the essential components of a chromosome, and they play a vital role in cell division, DNA replication, and genetic inheritance. Chromatids are the exact copies of a chromosome that are formed during the S phase of the cell cycle, and they are held together by a protein structure called the centromere. Each chromosome consists of two identical sister chromatids, which separate from each other during mitosis or meiosis.
