Describe differences between the structure of a duplicated chromosome before mitosis and the chromosome produced by separation of two chromatids during mitosis
What will be an ideal response?
Prior to mitosis, each chromosome consists of two chromatids. During anaphase the chromatids separate, so each chromosome now consists of a single chromatid. (Replication of this single-chromatid chromosome occurs during interphase to give rise to two chromatids.)
