During meiosis, crossing over occurs between View Solution The events shown below occur during different phases - A. Centromere splits, chromatids separate and move to opposite poles, chromatids are now called chromosome B. Chromosomes cluster at opposite poles, decondensation of chromosome, reappeara...
During anaphase identical sister chromatids separate and move towards opposite poles of the mitotic spindle. In the spindle, kinetochore microtubules have their plus ends embedded in the kinetochore and their minus ends at the spindle pole. Two models have been proposed to account for the movement ...
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
Related to Sister chromosome:Chromatids 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. ...

Therefore, chromatids are made of all the genetic material contained in a chromosome. What are sister chromatids in meiosis? Meiosis represents a process of cell division involving two rounds of cell division to produce sperm and eggs. Sister chromatids are formed during the first round of ...

Separation and Distribution: During mitotic anaphase or meiotic anaphase II, the cohesin protein complex cleaves leading to the dissolution of the cohesion between sister chromatids. As sister chromatids separate, they start moving towards the cell’s opposite poles, hence ensuring an equal distribution...
By analyzing the motion of GFP-tagged S. cerevisiae chromosomes, we show that kinetochore-microtubule attachments impose sufficient tension on sisters during prometaphase to transiently separate centromeric chromatin toward opposite sides of the spindle. Transient separations of 2–10 min duration occur ...
[3,52], but cannot distinguish between sister chromatids due to the two sisters sharing the same DNA sequence. Consequently, how the two copies of DNA in replicated chromosomes fold during G2 and how they resolve into separate cylindrical structures during mitotic entry remain important open ...
