What Is Kinetochore Class 11?

Kinetochore is a structure on chromatids at which the spindle fibres attach during cell division to pull the sister chromatids

sister chromatids
A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. ... The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis.
