What will happen to chromosomes that has two centromere?
centromere is place at which spindle fibers are attached if the centromere is lost then chromosome will lose its point for the attachement of the spindle fiber and then will not be able to take part in mitosis. chromosome is usually lost in this case.
What are chromosome pairs attached to?
Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
What is chromatid?
* the two exact copies of DNA that make up each chromosome.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
each chromosome consists of two identical "sister" chromatids
What is sister chromatids held together by?
Sister chromatids are held together at a region of highly condensed DNA called the centromere. The centromere region is very important during the process of cell division where chromosomes have to segregate into daughter cells. In addition, chromosomes are classified into different groups based on the position of the centromere
Two chromatids of a chromosome are attached at a point called?
The two chromatids of a chromosome are attached at a point called the centromere. It is the point which it is attached to a spindle fiber during the process of cell division.
What is a disk protein at the centromere region of the chromatid that serves as a platform for assembling microtubules?
When a chromosome has replicated and is preparing for division, the two chromatids are connected by the centromere. The centromere is the site where the kinetochore forms. The kinetochore forms the attachment with the spindle fibers.
Is a centromere an organized display of an organism's chromosomes?
No, the centromere is not an organized display of an organism's chromosomes. A centromere is the point of the chromosome where it is attached to a spindle during cell division.
How are DNA centromere chromosome and cromatid related?
They are letated because they are in the same process of cell division.
What is the area of a chromosome pair that attatches to a fiber stretching across the cell during cell division?
centromere
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.
What will happen to chromosomes that has two centromere?
centromere is place at which spindle fibers are attached if the centromere is lost then chromosome will lose its point for the attachement of the spindle fiber and then will not be able to take part in mitosis. chromosome is usually lost in this case.
Where do you find a centromere?
A centromere is a region of DNA typically found near the middle of a chromosome where two identical sister chromatids come in contact. It is involved in cell division as the point of mitotic spindle.
What are chromosome pairs attached to?
Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
What is chromatid?
* the two exact copies of DNA that make up each chromosome.
What is difference between centrosome and chromosome?
The difference between the aster of centrosome and chromosome is that the centrosome is a cell structure involved in the cell cycle that leads to cellular division. During the cell cycle, the cell grows and prepares itself to replicate chromosomes.Ê centrosome are outside the nucleus of the cell whereas chrosomes are inside the nucleus of the cell
What does the DNA do to prepare for division?
it replicates
