movement of chromosomes towards poles
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
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
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.
