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...
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 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. ...

Sister chromatids are formed during the first round of meiosis and remain attached to each other until anaphase II, where they become separated from each other. What are sister chromatids in mitosis? Sister chromatids refer to the pair of identical chromatids formed during interphase of mitosis....

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...
In contrast, when DNA has been replicated during S-phase, the sister chromatids can be used as templates for error-free repair through homologous recombination (HR)4. Cyclin-dependent kinase (CDK)-mediated activation of CtIP promotes the resection of the broken DNA ends by BRCA1/BARD1 and ...
[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 ...
When DNA containing such lesions replicates during S-phase, exchanges often occur between the two daughter molecules (Wolff et al , 1974). At the cytological level this becomes manifest as exchanges between the two sister chromatids of a metaphase chromosome. To visualize these exchanges, however,...
