Chromosomes condense before mitosis to allow them the ability to move smoothly, without becoming entangled and breaking. (So, they are conveniently packaged for cell division, in which the chromosomes must move to both poles of the cell.)
Why is it important for the chromosomes to condense?
It’s important for chromosomes to condense during mitosis because it allows for equal separation of the genetic material into the two daughter cells. …
Do chromosomes coil and condense in meiosis?
Meiosis: Type of cell division resulting in four haploid cells, the gametes. Meiosis I: Homologous chromosomes separate. … Prophase I: Stage of cell division in which the chromosomes coil and condense. Prophase II: Stage of cell division in which the chromosomes attach to the reforming spindle apparatus.
Why is it important for DNA to be coiled and condensed into chromosomes?
DNA is tightly packed up to fit in the nucleus of every cell. … Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.
Why does DNA condense coil during mitosis?
This condensation is needed to allow the chromosomes to move along the mitotic spindle without becoming tangled or broken during their distribution to daughter cells. DNA in this highly condensed state can no longer be transcribed, so all RNA synthesis stops during mitosis.
Why does DNA condense into chromosomes during mitosis?
Why does the DNA condense into chromosomes during cell division? … By condensing DNA into chromosomes, cells can align each chromosome (or during meiosis, each tetrad), along the metaphase plate. The spindle fibers can then pull apart sister chromatids (in Mitosis) or homologous chromosomes (Meiosis I).
