Is Sphase a phase of mitosis?
Yes it is a phase of mitosis. It the the phase in thich the chromosomes duplicate. As a result each chromosome ha 2 sister chromatids
How many chromatids have one chromosome?
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.
The two copies of DNA on each chromosome that form just before cell division?
Chromatids
What are the two copies of DNA on each chromosome that form just before cell division?
Chromatids
Each chromosome consists of 2 what?
Chromatids
What are chromosome pairs attached to?
Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
What makes up each chromosome?
A centromere and sister chromatids.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
each chromosome consists of two identical "sister" chromatids
What is anaphase 2?
The centromeres of each chromosome finally separate, and the sister chromatids come apart. The sister chromatids of each chromosome now move as two individual chromosomes toward opposite poles.
The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
What is the small section of a chromosome where sister chromatids attach to each other?
Centromere
What are the fibers that shorten and pull the chromatids apart called?
Microtubules pull the chromatids from the chromosome apart. Each former sister c
