Select the correct statements.
A. Tetrad formation is seen during Leptotene.
B. During Anaphase, the centromeres split and chromatids separate.
C. Terminalization takes place during Pachytene.
D. Nucleolus, Golgi complex and ER are reformed during Telophase.
E. Crossing over takes place between sister chromatids of homologous chromosome.
Choose the correct answer from the option given below:
A and C only
B and D only
A, C and E only
B and E only
Answers (1)
The correct answer is Option 2) B and D only.
Statement A: Tetrad formation is seen during Leptotene.
This statement is incorrect. Tetrad formation, also known as synapsis, occurs during the zygotene stage of prophase I of meiosis. During leptotene, chromosomes start to condense, but they have not yet formed tetrads.
Statement B: During Anaphase, the centromeres split and chromatids separate.
This statement is correct. During anaphase of mitosis or meiosis II, the centromeres split, and the sister chromatids separate, moving toward opposite poles of the cell.
Statement C: Terminalization takes place during Pachytene.
This statement is incorrect. Terminalization occurs during diplotene, not pachytene, which is a substage of prophase I of meiosis. Terminalization refers to the movement of chiasmata (sites of crossing over) towards the ends (terminals) of the homologous chromosomes.
Statement D: Nucleolus, Golgi complex, and ER are reformed during Telophase.
This statement is correct. During telophase of mitosis or meiosis, the nuclear envelope reforms, and the nucleolus, Golgi complex, and endoplasmic reticulum (ER) are reformed.
Statement E: Crossing over takes place between sister chromatids of homologous chromosomes.
This statement is incorrect. Crossing over, also known as recombination, occurs between non-sister chromatids of homologous chromosomes during prophase I of meiosis. It results in the exchange of genetic material between homologous chromosomes.
Therefore, the correct answer is Option 2) B and D only.
