Centromere is required for:

The centromere is required for the movement of chromosomes towards the poles during cell division. The centromere is a specialized region on a chromosome that serves as the attachment site for the microtubules of the spindle apparatus. So, the correct answer is option D. Notice that the other options are not correct. Transcription is the process of creating a complementary RNA copy from a DNA template, and it does not involve the centromere. Crossing over is the process of exchanging genetic material between homologous chromosomes, and it occurs during meiosis. Cytoplasmic cleavage is the process of dividing the cytoplasm of a cell during cell division, and it does not involve the centromere.
