Related to Sister chromatid:Sister chromatid exchange chro·ma·tid (krō′mə-tĭd) n. Either of the two daughter strands of a replicated chromosome that are joined by a single centromere and separate during cell division to become individual chromosomes. ...
The meaning of SISTER CHROMATID is either of the two identical chromatids that are formed by replication of a chromosome during the S phase of the cell cycle, are joined by a centromere, and segregate into separate daughter cells during anaphase. How to
The sister chromatids remain attached to each other through prophase and metaphase. During anaphase, the sister chromatids are separated from each other.What are Sister Chromatids? The replication of genetic material represents a central process of cell division in living organisms. In humans, there...
The meaning of CHROMATID is one of the usually paired and parallel strands of a duplicated chromosome joined by a single centromere.

During meiosis I the chromosomes of the cell align at its center in what is known ascrossing over. During this phase,homologous recombinationcan occur. During this time, sister chromatids are aligned with each other by recognizing long stretches of similar DNA sequences. They then exchange geneti...
