Answer:
Cell cycle regulators
Explanation:
Cell division is important for an organism for growth, repair and replacement of cells and tissues. In the unfortunate event of uncontrolled cell division, the organism makes more cells than it can produce. Growing cells have four phases
G1: Growth by doubling of cytoplasm and organelles
S: Synthesis of new DNA and doubling of chromosome number
G2: A second round of growth to prepare for cell division
M: Cytokineses and the formation of two very identical cells
In an attempt to end the uncontrolled cell division one would first look into factors that initiate the G1 phase; stopping the growth of an out of control cell before it starts.
A second approach is to look into manipulating the check points at G2 and M. If there are drugs that can interfere at this point the cell will not divide uncontrollably and the potential cancer will be interrupted.
Answer:
Explanation:
<em>Staphylococcus aureus</em> is a bacteria that causes food poisoning and a range of other diseases. Staphylococcal food poisoning is due to the consumption of a toxin produced by <em>S</em>. <em>aureus</em>. The toxin is usually preformed in the food, which means, one need not ingest the bacteria before developing food poisoning.
An important characteristic of the toxin is that it is heat stable. Although the bacteria itself is not heat stable, once it grows in the food and produces the toxin, heat treatment is no longer effective, because even though the bacteria will be killed off, the toxin will remain.
Another characteristic of <em>S</em>. <em>aureus </em>is that it can tolerate high amounts of salt.
<em>S</em>. <em>aureus</em> is also a normal flora of the skin, so it is almost always present on the skin of animals used as meat.
Because the bacteria is salt tolerant, and its toxin is heat stable, it is often the culprit in foods that have been processed with heat and/or by curing (salting), as is the case with processed ham, sausage and salted pork.
