Chromatid
Question 1: What is the difference between a chromatid and a chromosome?
Answer:
A chromatid is one-half of a duplicated chromosome attached to its duplicate at the centromere, while a chromosome is a single, long DNA molecule wrapped around histones and other proteins.
Question 2: What is the role of chromatids in cell division?
Answer:
Chromatids ensure that each daughter cell receives an identical copy of the genetic information during cell division.
Question 3: How do chromatids differ in mitosis and meiosis?
Answer:
Chromatids in mitosis are identical copies of a single chromosome, while chromatids in meiosis are homologous chromosomes that carry similar genetic information.
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.
