Explanation / Answer

-Ans- 1

a compex of DNA and protein housed in the nucleus- Chromatin

Ans2-

a stage of mitosis where sister chromatis seperate and moving to opposite lole- Anaphase

Ans-3

Cytokinesis- refer to the divission of cytoplasm and organelles

Ans-4

Telophase- last stage of the mitosis where spindle fibre dissipate

Ans-5

S-phase- prepartory event to mitosis where DNA replicates

Ans-6

Mitosis- refer to the divission of the nuclear material.

Ans-7

Nucleus-genetic material housed in the chromosome and Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.

Ans-8

Cell divission-the entire process whereby cells reproduces themselves

Ans-9

Metaphase- stage of the mitosis where chromatids align at the equitorial plane

Ans-10

Prophase-the first stage of the mitosis where chromosome become obsevable

Ans-11

In animal cell Centrioles-cytoplasplasmic organelles that help to produce spindle fibre

Ans-12

Kinetochore-attachment site of the spindle fibre on chromatids

Ans-13

DNA replication-process where DNA reproduces itself
