Final answer:
Sister chromatids are the identical copies of chromatin held together by cohesin at the centromere.
Step-by-step explanation:
The identical copies of chromatin held together by cohesin at the centromere are called sister chromatids. Sister chromatids are formed after DNA replication and remain attached at the centromere until they are separated during cell division.
The identical copies of chromatin held together by cohesin at the centromere are known as sister chromatids. They form after DNA replication in the S phase and are visible under a microscope due to their condensation.
The identical copies of chromatin that are held together by cohesin at the centromere are called sister chromatids. This occurs after DNA replication during the S phase of interphase. When the DNA condenses, the sister chromatids become visible under a light microscope, connected at a constricted area known as the centromere, which is highly condensed.
