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.
Sex Cell Production. Human sex cells are produced by a two-part cell division process called meiosis. Through a sequence of steps, the replicated genetic material in a parent cell is distributed among four daughter cells. Meiosis produces gametes with one-half the number of chromosomes as the parent cell. Because these cells have one-half the number of chromosomes as the parent cell, they are haploid cells. Human sex cells contain one complete set of 23 chromosomes. There are two stages of meiosis: meiosis I and meiosis II.
