∙ 9y agoA single round of DNA is replicated, and then two rounds of chromosomes are segregated. These events reduce the number of chromosomes.

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 does the chromosome duplicate itself in its life cycle?
will replicate itself during the synthesis phase within its life cycle
What chromosoMe develops muscle?
Muscle type is polygenic and is probably influenced early on during the gastrulation phase. Since there is substantial variation within families all the alleles are not on the same chromosome.
What phase is when each chromosome is connected to a spindle fiber?
During metaphase each chromosome attaches to spindle fibers. The centriole anchors the spindle fibers and helps in splitting the chromosome.
What happens to the number of chromosomes in mitosis?
There is no change in chromosome number. Just in the amount of chromatids. Because during synthesis each chromosome doubles and becomes sister chromatids.
During the cell cycle when would a chromosome consist of two identical sister chromatids?
During the interphase stage is whereby the chromosome consists of the two identical sister chromatids.
When are chromosome duplicate before or during mitosis?
Chromosomes are duplicated before mitisis in S phase of inter phase .
When does the chromosome number double?
The chromosome number only doubles when two haploid gametes form to produce a diploid zygote. Example: In humans, sperm cells and eggs have 23 chromosomes, the haploid number. Once they fuse, the number doubles to 46 chromosomes. You may be confusing this with chromosome replication. In chromosome replication, the number of chromosomes does not double, but the number of strands double. (A single stranded chromosome turns into a double stranded chromosome.) However, it is still considered a single chromosome, but with identical sister chromatids. This replication occurs during the S-phase of the cell cycle, before mitosis or meiosis.
When is s phase complet?
S phase is complete when each chromosome has been duplicated.
How many chromatids does each chromosome have before S-phase?
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
What is a dark staining body composed of 2 chromatids inside a cell during M-phase?
Chromosome
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.
Which phase balances chromosome in ceel cycle?
in S phase
During what phase do the two copies of each chromosome separate from each other and begin to move to opposite poles?
This occurs during anaphase.
When does the chromosome duplicate itself in its life cycle?
will replicate itself during the synthesis phase within its life cycle
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
What chromosoMe develops muscle?
Muscle type is polygenic and is probably influenced early on during the gastrulation phase. Since there is substantial variation within families all the alleles are not on the same chromosome.
