Question

A phase which is the reverse of prophase is

• A. Metaphase
• B. Interphase
• C. Telophase
• D. Anaphase

Answer 1

The correct option is C

Telophase

The correct option is C

Explanation of the correct option:

1. Telophase is the last phase of mitosis.
2. The daughter chromosomes separate and start forming chromatin reticulum.
3. This is the reverse of what happens in the prophase.
4. Prophase is the first stage of mitosis.
5. Chromatin fibres condense to form chromosomes in this stage.

Explanation of the incorrect options:

Option A:

1. Metaphase is the second phase in mitosis following the prophase.
2. Chromosomes are arranged at the equatorial plate of the nucleus.
3. Each chromosome is attached to spindle fibres at the centromere.

Option B:

1. Interphase: non-dividing phase.
2. The cell grows to maximum size.
3. It can be divided into the following stages:
   1. G₁ Phase: Volume of cytoplasm increases and protein synthesis occurs.
   2. S Phase: Synthesis of DNA takes place.
   3. G₂ Phase: Necessary spindle proteins are synthesized during this phase.

Option D:

1. Anaphase is the third stage of mitosis following metaphase.
2. Centromere division occurs and 2 sister chromatids separate.
3. Sister chromatids move towards opposite poles forming two groups of chromosomes.

Final answer: A phase that is the reverse of prophase is telophase.
