Meiosis is a specialized form of cell division that occurs to generate sperm and eggs with unique sets of paternal or maternal DNA; this process shuffles genetic information to promote the amazing variation that we observe in living organisms. In order to carry out two rounds of DNA separation with...
When a cell divides, it must assemble a microtubule-based structure called a spindle, which provides the forces that physically segregate the chromosomes. In most cell types the microtubules that comprise the spindle are nucleated and organized by centriole-containing centrosomes. In many species, however, oocyte meiosis is carried out in the...
