First Mr. Finley checked our homework. So you know since everybody in the class completed both assignments so if you were either absent or not paying attention you got 2 extra credit points. The term for cell reproduction is mitosis, or you may hear cell division. The 5 stages of mitosis are Interphase, then Prophase, Metaphase, Anaphase, and finally telophase. How to tell which fase a cell is in...you would have to look at the arrangement of chromosomes.

In mitosis, for a new cell to be made, a cell has to split in half. In order to split in half it needs new DNA for the new cell. This is how new cells are made. DNA is in its spegetti like strand and then it gets copied or replicated. Then there is new DNA for the new cell.To bond the two DNA strands there is something called a kineticore. Only Eukariotic cells may do this. Prokaryotic cannot do this because they do not have a nucleus. If you don't have a nucleus you can't make chromosomes. Whats the reason we need new cells some on asked? You need new cells because if you get a cut in your skin, you need more cells to to fill the cut. Also you would need more cells because since you grow, you would need more cells to to get bigger. You would have more skin, which would need more skin cells. That is just one example, but there are many. Everything is ready before mitosis occurrs such as proteins, new DNA, and chromosomes. Interphase is like your everyday for a cell except that one day where you do things differently like a holiday. This holiday is just metaphore for mitosis.
