dna, mutations, genes, and other diseases like cancer

enzymes are needed to begin and drive the cycle. they also direct the phases of the cell cycle

One way to control an enzyme is by altering the number of enzyme molecules. Two other ways are by altering the enzyme activity and compartmentalization.

One way to control an enzyme is through post-translational modification such as phosphorylation or glycosylation. Other ways to control enzymes are through enzyme induction, inhibition, or by compartmentalizing the metabolic pathways.

internal and external factors regulate the cell cycle

A cancer cell can grow uncontrollably in a number of ways. One of them is to bypass the cell cycle checkpoints (G1/S, G2/M, Spindle). Mechanistically this usually occurs due to mutations of p53 or Retinoblastoma (Rb) or related-proteins.

Cell Membrane is a semi-permeable part of a cell which takes part in exchanging enzymes, proteins or nutrients in between the environment and the cell. The Cell Membrane has a very lively effect to it and acts as a coating which also protects the cell in many ways.

1. secretes enzymes that "eat" the cell. 2. they produce chemical toxins which poison the body.

Cell growth is an essential requirement for cell cycle progression. While it is often held that growth is independent of cell cycle position, this relationship has not been closely scrutinized. Here we show that in budding yeast, the ability of cells to grow changes during the cell cycle. We find that cell growth is faster in cells arrested in anaphase and G1 than in other cell cycle stages. We demonstrate that the establishment of a polarized actin cytoskeleton-either as a consequence of normal cell division or through activation of the mating pheromone response-potently attenuates protein synthesis and growth. We furthermore show by population and single-cell analysis that growth varies during an unperturbed cell cycle, slowing at the time of polarized growth. Our study uncovers a fundamental relationship whereby cell cycle position regulates growth.

The best way to change a menstrual cycle would be to go on the birth control pill. Then, if one takes the pill continuously, the cycle will occur only when the pill is not taken.

Enzymes are proteins which act as catalysts for various reactions that occur in cells. (A catalyst speeds up a reaction without being permanently altered itself). Some proteins function in other ways like transporting substances across the cell membrane or providing structure. Therefore, all enzymes are proteins but not all proteins are enzymes. Uhm Ribozymes are enzymes that are not protein

1) Reactions that would not occur spontaneously on a biologically relevant time-scale occur quickly with increased efficiency because enzymes are able to lower the activation energy of the reaction. 2) Enzymes are used to control the specificity of the reaction. Products have the correct chirality. 3) Enzymes (especially in metabolism and signalling) are used as ways of integrating and regulating pathways.

You have no control over when your first menstrual period occurs, and extremely limited ways to influence the cycle (aside from pregnancy).

The easiest way to understand how viruses replicate is to study the life cycles of viruses called bacteriophages (bacteria eaters). Bacteriophages replicate by either a lytic cycle or a lysogenic cycle. The difference in these two cycles is that the cell dies at the end of the lytic cycle or the cell remains in the lysogenic cycle. The virus remains "hidden".

Generally, cell cycles are ways of producing more cells. Cells die off quickly ,but most reproduce before death. Cells can reproduce w/o a 'mate' or other cell.

Many enzymes are affected by changes in temperature. Cells can regulate the activities of enzymes in many ways. Most cells contain proteins that help turn key enzymes "on" and "off" at critical stages in the life of the cell. Enzymes play essential roles in regulating chemical pathways, making materials that cells need, releasing energy, and transferring information

Cell division has three ways it prevents problems in cell growth. The three ways are as follows: when cells increase, when cells decrease, and preventing cell loss.

Humans alter the nitrogen cycle in various ways. One of the common ways is the application of nitrogen fertilizers on crops.
