Why is it important to keep sister chromatids together?

In cell division, after replication of the cell’s chromosomes, the two copies, called sister chromatids, must be kept together to ensure that each daughter cell receives an equal complement of chromosomes. … In higher organisms, DNA is packaged into chromosomes.

Why is it important for sister chromatids to be attached to each other during the beginning phases of mitosis?

Why is it important for sister chromatids to be attached to each other during the beginning phases of mitosis? The chromatids need to pass on a copy of their genetic information to one another. Necessary for DNA replication between two sister chromatids.

Why is it important that the chromatids remain attached prior to being pulled apart during anaphase?

Because the separation of the sister chromatids during anaphase is an irreversible step, the cycle will not proceed until the kinetochores of each pair of sister chromatids are firmly anchored to spindle fibers arising from opposite poles of the cell.

What would happen if both sister chromatids move to the same pole?

At meiosis I, sister chromatids attach to the same spindle pole while homologous chromosomes attach to the opposite spindle pole via the spindle microtubules. These chromosomal attachments to the spindle poles result in meiosis I-specific chromosome segregation.

What is the importance of chromosome replication during interphase?

Chromosome duplication is essential so that each daughter cell receives equal number of chromosomes from the parent cell. Hence, it is vital to generate an exact copy of the parent cell.

Why do sister chromatids stay together in anaphase 1?

during ANAPHASE 1, cohesion molecules are activated by SEPARASE allowing homologs to separate. However, the cohesion of sister chromatids are protected from the action of separase by the protein SHUGOSHIN and are unaffected. RESULT: SISTER CHROMATIDS STAY TOGETHER DURING ANAPHASE 1.
