What phase do sister chromotids separate?
Anaphase
During the s phase chromosomes are converted to what form?
Sister Chromotids
What is the difference between a Sister and a Non-Sister Chromotids?
I think that sister chromatids probably look more like each other because, well, they are sisters. I look like my sisters.
Is it necessary that the nuclear membrane disintegrates during mitosis?
the machinary required to sperate the sister chromotids (each set of DNA) is outside the nucleus, and therefore requires access to the DNA. also the nucleus is quite small, so allowing the DNA access to the rest of the cell allows for more separation (i.e. a greater distance between the two sister chromotids can be acheived).
Why is it so important that the sister chromotids separate equally during anaphase of mitosis?
Can't reproduce unless exactly half. (Offspring will be genetically deformed.)
What the two copies of chromosomes are called?
Chromosomes are roughly made up of proteins and DNA
At the end of what phase and cytokinesis haploid cells contain chromosomes that each consist of two sister chromotids?
At the end of telophase I and cytokinesis, there are two haploid cells with chromosomes that consist of two sister chromatids each
When do chromotids separate during mitosis?
Anaphase.
The area where a pair of chromotids is attached is the?
Centromere
What is the area where a pair of chromotids is attached?
The centrometre
What is only a single member of a pair of chromosomes present in a cell?
In a chromosome pair, a single chromosome is called a chromatid and the two chromotids in the pair are commonly called "sister chromatids."
How many chromotids are present in a chromosome at the beginning of mitosis?
2
