☆☆☆☆☆A chromosome is a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order. It is also known as tightly wound DNA. It is a structure that DNA wraps around.
MORE INFORMATION:
A chromosome is an organized structure of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.
Chromosomes vary widely between different organisms. The DNA molecule may be circular or linear, and can be composed of 10,000 to 1,000,000,000 nucleotides in a long chain.
Cells may contain more than one type of chromosome; for example, mitochondria in most eukaryotes and chloroplasts in plants have their own small chromosomes.
Chromosomes are the essential unit for cellular division and must be replicated, divided, and passed successfully to their daughter cells so as to ensure the genetic diversity and survival of their progeny.
Chromosomal recombination plays a vital role in genetic diversity. If these structures are manipulated incorrectly, through processes known as chromosomal instability and translocation, the cell may undergo mitotic catastrophe and die, or it may aberrantly evade apoptosis leading to the progression of cancer.
In practice "chromosome" is a rather loosely defined term. In prokaryotes and viruses, the term genophore is more appropriate when no chromatin is present. However, a large body of work uses the term chromosome regardless of chromatin content. The simplest genophores are found in viruses: these DNA or RNA molecules are short linear or circular genophores that often lack structural proteins.
Chromosomal DNA encodes most or all of an organism's genetic information; some species also contain plasmids or other extrachromosomal genetic elements.

One of the major aspects of life is self replication, or reproduction. If cells didn't divide, then populations of organisms would not form, and evolution would be impossible. The more proximate cause is that as cells grow and ingest food, there is a limit to how big they can become before the cell wall no longer supports the cytoplasm. At or before this point, the cell must divide or it will lyse (split open) and die.
During telophase the cell membrane gets "pinched" and the orgenelles and DNA are split. following telophase is cytokinesis when the cell membrane is sealed off and the mother cell becomes two sister cells.
The final stage of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes.

In telophase nuclear membrane is begin to reform at both ends of the cell and spindle fibers disappear. chromosomes uncoil and return to chromatin form in preparation for Interphase. Cytokinesis coincides with this stage of mitosis.
All of this is true but a much easier answer to this question is that telophase is when a new nucleus forms around each copy of dna.
sex cells
They pull the cell membrane in.
They Split The Cell During Cytokinesis.
M Phase
S Phase - period of DNA replication - 10% shorter than G1.
After G1 phase S phase occurs.
Anaphase
Two haploid cells
it would prevent tumor cells from reproducing.
in plants, a new cell wall forms to split the cell
