What is the significance of the chromosomes condensing prior to being moved?
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.
What is the purpose of chromosome condensation?
Chromosome condensation is mediated by the condensin complex, among other proteins, and is necessary to prevent chromosomes from being entangled during chromosome segregation.
What is the purpose of chromatin condensing into chromosomes?
Chromosome condensation is one of the major chromatin-remodeling events that occur during cell division. The changes in chromatin compaction and higher-order structure organization are essential requisites for ensuring a faithful transmission of the replicated genome to daughter cells.
Why is it important for the chromosomes to condense during prophase of mitosis?
Chromatin, a substance that contains genetic material such as DNA, is normally found in a loose bundle inside a cell’s nucleus. During the prophase of mitosis, the chromatin in a cell compacts to form condensed chromosomes; this condensation is required in order for the cell to divide properly.
Why does DNA have to condense down into chromosomes before the cell divides?
Prior to mitosis, the cell copies its DNA so that it contains two copies of each chromosome. … Condensing the DNA into tightly packed chromosomes makes the process of chromosome alignment and separation during mitosis more efficient.
What is the physical advantage of the chromatin coiling and condensing to form short chromosomes at the onset of mitosis?
The supercoiling of chromatin into compact chromosomes enables the efficient transfer and separation of chromosomes in the succeeding stages of mitosis. With the chromosomes compacted, it is much easier to transfer them to the metaphase plate.
What is meant by condensation of chromosome material?
[¦krō·mə‚sōm ‚kän·dən′sā·shən] (cell and molecular biology) The process whereby chromosomes become shorter and thicker during prophase as a consequence of coiling and supercoiling of chromatic strands.
Why do you think that chromatin condenses into chromosomes before mitosis occurs?
Although chromatin changes are already detectable before nuclear envelope breakdown, this leads to further chromatin condensation and allows assembly of the mitotic spindle, which will capture, move and align the individualized chromosomes at the metaphase plate and segregate the disengaged chromatids.
What is chromatin material and how does it change just before the cell divides?
The DNA + histone = chromatin
As the cell initiates divisions by either meiosis or mitosis. During the interfaces, DNA is combined with the proteins and organized into a structure called chromatin. This chromatin is a thread like structure which condenses to form chromosomes just before the cell division occurs.
