What is the function of centromore in mitosis?
It splits and pushes chromatids to migrate to either side of the cell.
What is the function of polar?
The function of polar microtubules is to elongate while the centromere microtubules shorten, so the chromatids can reach the opposite poles (centrioles) of the cell.
What holds 2 chromatids together?
The centromere is the part of a chromosome that links the sister chromatids together. There are two types of centromeres. Regional centromeres have DNA sequences that contribute to, but do not define function. Point centromeres are smaller and more compact, but the DNA sequences are necessary and sufficient to specify the centromere's identity and function.
What condenses into an X shape before mitosis?
Chromatids condense into an X shape before mitosis. Chromatids are identical strands of chromosomes. After duplication there are 12 chromatids that are in 3 pair of homologous chromosomes.
What is the connector for sister chromatids?
Centromere connects the sister Chromatids
What is the function chromatids?
Chromatids are the little strings of DNA inthe process called mitoisis
Specify the location and function of the centromere?
The centromere is found in the middle of two sister chromatids. The sister chromatids are connected by the centromere in order to form a chromosome.

What is the difference between recombinant and parental chromatids and how do they arise?
Parental chromatids are chromatids that have a combination of alleles identical to the parents and Recombinant chromatids are chromatids that have a mix of alleles from both parents.
What condenses into an X shape before mitosis?
Chromatids condense into an X shape before mitosis. Chromatids are identical strands of chromosomes. After duplication there are 12 chromatids that are in 3 pair of homologous chromosomes.
What is the connector for sister chromatids?
Centromere connects the sister Chromatids
What chromatids are attached at the centromere?
Strictly speaking, chromatids aren't attached; they grow that way. They are, however, formed during Prophase of mitosis and Prophase I of meiosis. A: CENTROMERES
2. What are sister chromatids When do the separate?
In anaphase I the sister chromatids remain attached, while in anaphase II the sister chromatids separate.
What evidence supports the observation that sister centromeres behave as a unit during meiosis you?
Data from electron microscopy studies suggests that the centromere/kinetochore complex of sister chromatids is compacted. The kinetochores then capture microtubules in a way that allows the kinetochores of sister chromatids to function as a single unit.
