Question

Select the correct statements.

1. Tetrad formation is seen during Leptotene.
2. During Anaphase, the centromeres split and chromatids separate.
3. Terminalization takes place during Pachytene.
4. Nucleolus, Golgi complex and ER are reformed during Telophase.
5. Crossing over takes place between sister chromatids of homologous chromosome.

Choose the correct answer from the options given below:

• A. B and D only
• B. A, C and E only
• C. B and E only
• D. A and C only

Answer 1

The Correct Option is A

To determine the correct statements, we need to analyze each statement regarding cell division:

1. Incorrect: Tetrad formation occurs during the Pachytene stage of meiosis, not Leptotene.
2. Correct: During Anaphase, the centromeres split, and sister chromatids (now individual chromosomes) are pulled to opposite poles.
3. Incorrect: Terminalization occurs during the Diplotene stage, not Pachytene.
4. Correct: During Telophase, the nucleolus, Golgi complex, and endoplasmic reticulum (ER) are reformed as the cell begins returning to its interphase state.
5. Incorrect: Crossing over takes place between non-sister chromatids of homologous chromosomes during Prophase I of meiosis.

Based on this analysis, the correct statements are B and D. Therefore, the correct option is:

B and D only
