How many coiled DNA molecules has an S phase have at the end?
At the end of the S phase, each DNA molecule is duplicated and consists of two coiled sister chromatids. This results in each chromosome having two identical copies of DNA.
What is a dark staining body composed of 2 chromatids inside a cell during M-phase?
The dark staining body composed of 2 chromatids inside a cell during M-phase is called a chromosome. Chromosomes are formed when the DNA in a cell is tightly coiled and condensed to facilitate cell division. Each chromosome consists of two sister chromatids that are held together at a structure called the centromere.
How does a duplicated chromosome differ from a chromatid?
Chromosomes are what make up your genetic material. During interphase when the chromosomes are duplicating, they remain attached to their duplicated with a centromere. When they are connected with their duplicate, each individual of this pair is called a chromatid. So a duplicated chromosome is made up of two chromatids which are identical to each other.
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.
In which phase does chromosome replication occur?
Chromosome replication occurs during the S phase of the cell cycle. This is when DNA is synthesized to ensure that each daughter cell receives an identical copy of the genetic material during cell division.
How many coiled DNA molecules has an S phase have at the end?
At the end of the S phase, each DNA molecule is duplicated and consists of two coiled sister chromatids. This results in each chromosome having two identical copies of DNA.
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.
When is Phase complete?
S phase is complete when each chromosome has been duplicated.
Number of DNA molecules in a chromosomes?
Each chromosome contains a single DNA molecule that is highly compacted and coiled around proteins. This single DNA molecule contains all the genetic information for an organism.
What is a dark staining body composed of 2 chromatids inside a cell during M-phase?
The dark staining body composed of 2 chromatids inside a cell during M-phase is called a chromosome. Chromosomes are formed when the DNA in a cell is tightly coiled and condensed to facilitate cell division. Each chromosome consists of two sister chromatids that are held together at a structure called the centromere.
In eukaryotic cells each chromosome has?
In eukaryotic cells, each chromosome has one or more DNA molecules, which are tightly coiled around proteins called histones. These DNA-histone complexes form chromatin fibers, which condense further to create distinct chromosomes during cell division.
When the cell copies its DNA in order to have full sets of chromosome is what phase?
The process of DNA replication occurs during the S phase (synthesis phase) of the cell cycle. During this phase, each chromosome is duplicated, resulting in two identical sister chromatids for each chromosome. This ensures that when the cell divides, each daughter cell will receive a complete set of chromosomes.
When is the S phase completed?
when each chromosome has been duplicated
What is the Phase of mitosis in which microtubules connect the centromere of each chromosome to the poles of spindle?
a microscopically small tuble, it is the introcellular support of the cytoskeleton and also helps in transport of certain protein molecules.
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
The phase of mitosis in which microtubles connect the centromere of each chromosome to the poles of the spindle is?
Metaphase
