    00:01 So being familiar with the phases of the cell cycle, we can now move on and look in more detail at mitosis or cell division.

    00:10 But first, in order to understand cell division, we have to learn to speak the language of chromosomes.

    00:17 So by the end of this lecture, you should be pretty familiar with that language.

    00:22 In addition, you'll be able to describe how DNA winds itself up from the chromatin form into chromosome form because that needs to happen before the DNA can separate during mitosis.

    00:35 In addition, you'll be able to diagram the different phases that we see in mitosis specifically what is happening in each phase, as well as being able to differentiate between two critical terms, mitosis, which is nuclear division, and cytokinesis, which is actual cellular division where we divide up all the components of the cytoplasm.

    00:59 So in order to begin, let's take a look at the cell cycle. We know that we have G1, G2 and S phase.

    01:07 Growth happening in G1. These are all the parts of interphase.

    01:10 S phase is where we see synthesis of the DNA, that's a very important phase.

    01:15 And then G2, we're preparing for mitosis.

    01:18 But this lecture is going to focus on each of these phases of mitosis.
