Revision as of 16:34, 2 December 2011

Sister chromatids are 2 identical strands of DNA, held together at the Centromere after being copied in the S-Phase of the Cell cycle ^[1]. During Mitosis chromatids separate, each entering identical daughter cells.

Dyad

A dyad^[2] is a sister pair of chromatids. These are generated in prophase 1 of meiosis. The two sisters line up side by side and share a centromere.
