The centromere, a specialized region of the chromosome, plays a crucial role in holding the individual chromatids together, ensuring their proper segregation during cell division. Composed primarily of heterochromatin, the centromere binds to specialized proteins called kinetochores, which in turn attach to spindle fibers during mitosis and meiosis. This intricate connection enables the equal distribution … Read more

Meiosis, a vital process in reproduction, produces gametes, which are essential for sexual reproduction. During meiosis, genetic material is halved, ensuring that each gamete receives a single set of chromosomes. The primary function of meiosis is to produce sperm and eggs, which carry half the number of chromosomes as the parent cell. Moreover, meiosis facilitates … Read more
