In this video, we start by looking at chromosomes. We then explore the cell-cycle involving mitosis and why this is important.

Completely agree although i get Grade 4/5s in science i feel like i barely know anything.First time reviisng actually.and how they dragged on the topic of B2 for like 2 months but it was worth it when i did the mock on B2 i got a 6 on the paper.But it aint worth anything anymore as i had forgotten it.
