Year three was a hell of a lot harder than year one in primary school. lol you are taking to the extreme but i have heard some freinds say that second year is the hardest for some reason. (Original post by Aspiringlawstudent).
In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set.
Then the cell goes through two consecutive rounds of nuclear divisions, termed meiosis I and meiosis II, according to the journal Nature. As a result, the overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell has half the number of chromosomes as the original parent cell. The mechanisms of mitosis and meiosis are very similar. Meiosis I. Prior to meiosis I, the duplicated chromosomes, also known as sister chromatids, fuse together.
