Cell Division- Mitosis As a prison cell grows, more contain is placed on exchange of materials (nutrients intake, waste removal intake). also more demands argon placed on its DNA As a cell grows its surface field of study grows slow (Pie R Squ ard) than its volume (Pie R Cubed). When the ratio of get along Area/Volume r separatelyes a specific acid chemicals called cyclins cast down the cell division process. What atomic number 18 chromosomes? They are a protein social structure that contain DNA (genetic information) gentlemans gentleman spend a penny 23 pairs of chromosomes or 46 in EVERY cell. In other words from each one cell had the complete library of information. (Fruit flies allow 4 pairs of chromosomes or 8 chromosomes) Chromosomes cannot be seen in a cells consequence until the cell duplicates all the chromosomes just before mitosis (cell division). When the DNA and chromosomes have doubled, each chromosome has an identical pair. We call these pairs chroma tid pairs. They are held together by a small microtube called a centromere. Two Identical Chromatid held by a centromere (dot) Cell Cycle All cells go through a cycle. The longest recrudesce is interphase, a offend (G1) in time where the cell grows and functions only when does not reproduce.

bordering comes the S phase. In this phase DNA is replicated and Chromosomes duplicated in Chromosome pairs. afterwards this comes a short G2 phase where molecules and organelles that cause Mitosis are produced. The furthermost phase is M or Mitosis phase. Mitosis has four locomote: A. Prophase B. Metaphase C. Anaphase D. Telephase the cell seperates into two new cells. In animal cells it totally seperates, this is called ! cytokinesos. If you deficiency to get a full essay, order it on our website:
