What else can I help you with?
During which phase of mitosis do the paired chromatids break apart at the centromere to become individual chromosomes before moving toward opposite poles of the cell?
The chromatids break apart at the centromere during the anaphase of mitosis. This is when the spindle fibers pull the individual chromosomes toward opposite poles of the cell.
The moving part of each of homologous chromosomes during anaphase you of meiosis is called?
The moving part of each homologous chromosome during anaphase I of meiosis is called a chromatid. Each chromatid is a single strand of DNA that is duplicated during the S phase of the cell cycle and remains joined to its sister chromatid at the centromere until they separate during anaphase.
What is the center of a chromosomes called?
The center of a chromosome is a centromere.
In what phase of mitosis do the sister chromatids move to opposite poles of the cell?
In the third stage, anaphase, the sister chromatids ofeach replicated chromosome begin to separate.Fibers pull the centromere apart and chromatidsmove away from each other, toward opposite ends of thecell.
Sister chromatids are attached to each other at an area called the?
The chromatids are attached to each other at the Centromere. Hope that helps have a nice day.
When does a centromere divide?
It is in Anaphase. ;)
What phase do centromeres break?
Centromere splitting is something that happens to the Chromosomes during the M Phase (Mitosis) of cell division. During Anaphase (a phase in the M Phase), the centrioles that have sent out spindle fibers and are at opposite poles just tug at the centromere of the Chromosome, causing the centromere to split. Anaphase is basically centromere splitting, where the spindle fibers from the centrioles split the chromosome in half at the centromere.
When do the pair of chromatids break apart at the centromere?
Anaphase
What divides during anaphase that allows the identical chromosomes to separate?
centromere
What has happen to the centromere just at the end of metaphase or the very beginning of anaphase?
it divides
During which phase of mitosis do the paired chromatids break apart at the centromere to become individual chromosomes before moving toward opposite poles of the cell?
The chromatids break apart at the centromere during the anaphase of mitosis. This is when the spindle fibers pull the individual chromosomes toward opposite poles of the cell.
What happens during anaphase 1and 2?
Anaphase 1: 1. Breakdown of proteins responsible for sister chromatid cohesion along chromatid arms allows homologs to separate. 2. The homologs move toward opposite poles, guided by the spindle apparatus. 3. Sister chromatid cohesion persists at the centromere, causing chromatids to move as a unit towards the same pole. At anaphase 1 of meiosis, the replicated chromosomes of each homologous pair move toward opposite poles, but the sister chromatids of each replicated chromosome remain attached. In anaphase of mitosis, by contrast, sister chromatids separate. Reference Cambell et al. Biology (8th Ed) 2008. Benjamin Cummings. pg 254-257
Which phase of mitosis does the centromere divide chromatids split and identical chromosome move to opposite ends of the cell?
metaphase I of meiosis
WHAT begins with the separation of centromeres?
Anaphase begins with the separation of centromeres. During anaphase, the two sister chromatids, each with its own centromere, are pulled apart towards opposite poles of the cell by the spindle fibers.
