Question

At the end of prophase,when a cell viewed under the microscope does not show

• A. Initiation of assembly of spindles
• B. Duplicated centrioles
• C. Nuclear membrane and nucleolus
• D. Condensed chromosomes

Answer 1

The correct option is C Nuclear membrane and nucleolus

Completion of prophase is marked by the following characteristic events:
1. Chromosomal material condenses.

2. Chromosomes are seen to be composed of two chromatids attached together at the centromere.

3. Initiation of the assembly of mitotic spindle, the microtubules, the proteinaceous components of the cell cytoplasm help in the process.
4. When viewed under the microscope they do not show golgi complexes, endoplasmic reticulum, nucleolus and the nuclear envelope.

So, the correct answer is 'Nuclear membrane and nucleolus'.
