In dividing cells, most of the celrs growth occurs during 5. The and plays a role in cell division 6 During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed interphase is a cell structure consisting of microtubules, which forms during early mitosis er Settings chromatin form called when the rest of the cell 7. In most eukaryotes, dvision of the nucleus is followed by divides 8. The are the organzing centers for microtubules involved in separating chromosomes during mitosis 5/3/2018 Type here to searchExplanation / Answer
1. Sister chromatids
The two sister chromatids are held together by centromeres
2. Centromere
This holds together the chromatids untill the separation at metaphase.
3. Kinetochore
It is a protein complex where the microtubules attach to the chromosomes.
4. Interphase
It is the longest phase characterized by active protein synthesis to prepare the cell for division.
5. Centrosome
It helps in the nucleation and formation of microtubules.
6. Chromatin
It is the uncondensed DNA complexed with proteins.
7. Cytokinesis
It divides the cell into two daughter cells. It occurs after nuclear division.
8. Mitotic spindles
These arrange the chromosomes for separation.
a) Non-dividing cells exit cell cycle.
b) At this point, cell commits to go through cell cycle. Also called as restriction point.
c) DNA replicates, allowing doubling of DNA
d) Centrosome replicates, which helps in nucleation of microtubules.
e) Mitotic spindle begins to form, which facilitate separation of chromosomes.
f) Cell divides forming two daughter cells
