Question

A cell at prophase shows all, except Condensation of chromatin, Spindle fibre formation ,Nucleolus reappearance ,Disintegration of nuclear membrane​

Answer 1

Explanation:

During prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids ). During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers.

Answer 2

A cell at prophase shows all, except Condensation of chromatin, Spindle fibre formation ,Nucleolus reappearance ,Disintegration of nuclear membrane​

• development of spindle fibres, nucleolus emergence again, nuclear membrane detachment The chromatin, a combination of DNA and proteins found in the nucleus, condenses during prophase. The development of discernible chromosomes is caused by the coiling and tightening of the chromatin. One well-organized piece of DNA makes up each chromosome.
• The chromatin is organised in a row and condensation is at its peak during the subphase known as metaphase.
• The nuclear envelope degrades during the prophase. Chromosomes are formed by the chromatin compacting. Chromosomes align themselves along the metaphase plate during this phase.
• Following the end of the G2 phase of interphase, the first step of mitosis is known as prophase. The parent cell's chromosomes, which were duplicated during S phase, condense and get much smaller than they did during interphase during prophase.
