Centromere is required for
transcription
crossing over
cytoplasmic cleavage
movement of chromosomes towards poles
The Correct Option is D
Solution and Explanation
Centromeres are essential for the proper segregation of chromosomes during cell division. They serve as attachment points for spindle fibers, which help move the chromosomes towards the poles of the cell during both mitosis and meiosis. This ensures that each daughter cell receives the correct number of chromosomes.
So, the correct option is (D): movement of chromosomes towards poles

Questions Asked in NEET exam
- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Concepts Used:
Eurkaryotic Cells - Golgi Apparatus
The Golgi apparatus is also known as the Golgi complex or the Golgi body. The term is derived from Camillo Golgi, the scientist who discovered the organelle. It can be found in all eukaryotic cells, including plants and animals. They are membrane-bound organelles found in the cell's cytoplasm.
Formation of acrosome: The acrosome is a component of the tip of animal sperms that aids in the digestion of the egg or ovum covering sheath during fertilisation. The Golgi complex produces it with the help of its vesicles.
