2) Sister chromatids are pulled apart
3) Nuclear membrane and nucleolus reappear
4) Centrioles duplicate and move towards opposite poles
Prophase
Telophase
Metaphase
Anaphase​

Answer 1

Required Answer:-

1) Formation of spindle fibres - Prophase

• It is the first phase of M-phase.
• Condensation of chromatin fibre occurs.
• Formation of spindle fibres from tubulin protein synthesized in the G2 phase.
• Disappearance of NM and cell organelles.

2) Sister chromatids are pulled apart - Anaphase

• Centromere division and separation of sister chromatids.
• There are two subphases: Early and late.
• Depolymerization of spindle fibres.

3) Nuclear membrane and nucleolus reappear - Telophase

• Just opposite of prophase events.
• Decondensation and reappearance.

4) Centrioles duplicate and move towards opposite poles - Metaphase

• Chromosome arranged at equator.
• Formation of metaphasic plate$.$

Answer 2

Required Answer :-

Correct matching is

1 - a

2 - d

3 - b

4 - c

More to know :-

Prophase :- it is the first phase of the mitosis in which the duplicate genetic things are carried by the nucleus of the parent one.

Telophase :- It is the last phase of mitosis. It separate the parent cell into two identical daughter cells.

Metaphase :- It is the second phase in which the eukaryotic cell cycle occur.
