Mitosis and Meiosis Practical Report
| CELLULAR DIVISION AND REPLICATION WITHIN MITOSIS AND MEIOSIS ABSTRACT
The processes of mitosis and meiosis were examined along with their frequency as well as each of the different steps and their time duration. It was found that the interphase stage of both mitosis and meiosis was the longest of all the stages as this was where most of the ‘action’ was happening such as cell growth and duplication of all cell organelles and chromosome replication also. It was also found that mitosis and meiosis have similar stages, however, they also have a lot of differences such as the end result and what is happening throughout each stage.
INTRODUCTION
The two processes of cellular division are mitosis and meiosis. The normal process of cellular division is mitosis where two daughter nuclei are produced and have equivalent genetics to the parent nucleus. However, meiosis is the variation of cellular division where gametes are produced and each daughter cell yields half the DNA from the parent cell. Also, before mitosis and meiosis can occur chromosomes must replicate in order to produce identical chromatids and they are each connected to a centromere.
As pointed out before, mitosis is the process of cell division and the end result of this is duplicated chromosomes with two daughter nuclei that are both identical to the parent nucleus. Mitosis can be used for growth, repairing, and asexual reproduction for an organism. There are five main steps in the mitosis cycle and they are interphase, metaphase, anaphase and telophase. Firstly, interphase has a lot going on and starts off by the cell increasing in size and mass and duplication of the cell organelles, such as the ribosomes, mitochondria, endoplasmic reticulum and centrioles. The DNA is then synthesized along with chromosomal duplicates being produced. At the centromere the chromosomes are then joined together, called sister chromatids. Next is prophase and the chromosomes become dense and visible as
