Mitosis Phases And Important Structures

Question 1

Chromatin

Answer 1

Unpackaged chromosome state in interphase

Bowl of spaghetti

Question 2

Chromosome

Answer 2

Linear pieces of Dna
Contains genes

Unreplicated before Sphase- 1 piece

Replicated after Sphase- 2pieces

Question 3

Chromatid

Answer 3

Half of replicated chromosome

1 chromatid on either side of a centromere

Question 4

Centromere

Answer 4

Protein structure connecting sister chromatids of a replicated chromosome

Question 5

Spindle fibre/ centriole

Answer 5

Microfibre strands spectate chromosomes in PMA

Synthesized by centrioles
Attach to protein of centromere

Question 6

Interphase (G2)

Answer 6

Growth and differentiation

Replicated chromosomes in chromatin form

Question 7

Prophase

Answer 7

Nuclear envelope/nucleolus disappear

Replicated chromatin condense into chromosomes

Spindle fibres from centrioles attach to centromere

Question 8

Metaphase

Answer 8

Spindle fibres shorten pulling chromosomes- line up on equator

Question 9

Anaphase

Answer 9

Replicated chromosomes pull apart

Sister chromatids are pulled to the poles

Become unreplicated chromosomes

Question 10

Telophase

Answer 10

Spindle fibres disappear

Nuclear envelope and nucleolus reappear

Unreplicated chromosomes relax in chromatin
Cleavage forms

Question 11

Telophase

CYTOKENESIS

Answer 11

Cleavage forms

Microfilaments pinch off two daughter cells by dividing cytoplasm

Question 12

Daughter cell in interphase (G1)

Answer 12

After telophase/cytokenesis
Two cells from 1
Genetically identical to parent cell
Cells are now in G1 of interphase
