Triss [41]

Answer:

Explanation:

1. Chromatids

Chromatin condenses and forms more tight and compact chromosomes. Chromosomes are seen to be composed of two chromatids.

2. Centromere

Sister chromatids are attached together at the centromere.

3. Kinetochores

Chromosomal microtubules attach to kinetochores of chromosomes.

4. Interphase

Interphase is the period between cell divisions, is a time when the cell grows and forms various necessary proteins. Interphase lasts for days or weeks whereas mitosis lasts for hours.

5. Mitotic spindle

Chromatin gets packed into mitotic chromosomes, which are segregated by a mitotic spindle.

6. Chromatin

Chromatin is the complex form of DNA and proteins that condense into more compact chromosomes.

7. Cytokinesis

Mitosis leads to division of duplicated nuclei material into daughter nuclei but the cell is divided into two daughter cells when a furrow is formed into the center of the cell by a process called cytokinesis.
