Verified step by step guidance

Understand that chromosomes are structures within cells that contain DNA and protein, and they play a crucial role in cell division.
During cell division, specifically in the S phase of interphase, each chromosome is replicated to form two identical copies.
These identical copies are known as sister chromatids. They are held together by a region called the centromere.
Differentiate between sister chromatids and other terms: Chromatin refers to the material that makes up chromosomes, alleles are different versions of a gene, and homologous chromosomes are pairs of chromosomes that have the same genes but may have different alleles.
Recognize that the correct term for identical duplicate chromosomes held together by a centromere is 'sister chromatids'.
