In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...

In the beginning, you were just some genetic material. In order to make you, your biological mom and dad both had to participate in an effort to pitch in one gamete each — a sperm cell and an egg cell ...

As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from asexual to ...

Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two ...

How is the same process responsible for genetic recombination and diversity also the cause of aneuploidy? Understanding the steps of meiosis is essential to learning how errors occur. Researchers' ...

The activity on this page was designed by science education experts to explain and visualise the three stages of mitosis. By interacting with the activity, you'll see the mitosis phases and ...

This activity has been carefully designed to help you see and understand exactly what’s happening during each stage of mitosis. Mitosis will produce two daughter cells which are genetically identical ...

The chromosomes align along the metaphase plate. As in mitosis metaphase, (and unlike meiosis metaphase I), fibers from the centrioles begin to pull on each one of the chromosomes from both directions ...
