contact inhibition and "go, no-go" switches
Cells stop dividing because the telomeres, protective bits of DNA on the end of a chromosome required for replication, shorten with each copy, eventually being consumed, as described in the article on telomere shortening.
Cells know to stop dividing through mechanisms such as contact inhibition and the presence of regulatory proteins. Contact inhibition occurs when cells encounter neighboring cells, triggering signals that halt further division. Additionally, tumor suppressor proteins like p53 can detect DNA damage or cellular stress, leading to cell cycle arrest to prevent the propagation of damaged cells. These regulatory pathways help maintain tissue homeostasis and prevent uncontrolled cell growth.
There are three primary ways to treat cancer: chemotherapy, radiation, and surgery. Chemotherapy uses medication that are toxic to rapidly dividing cells, like cancer cells. Radiation works similarly, but exposed the diseased part of the body to radioactive waves. Surgery is removal of the tumor, when possible.
I don't know sadly
By cutting along its lines of symmetry
All cells have DNA
Three ways to stop a virus from spreading include washing your hands, being mindful when using carts at the grocery store, and staying at home if you know you are sick. This will prevent others from catching your illness.
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.
One of the ways i know is.....Birth Control. Also, three words... The... Hunger... Games
Cancer cells differ from normal cells in several ways. They grow and divide uncontrollably, ignore signals to stop growing, can invade nearby tissues, and can spread to other parts of the body. Additionally, cancer cells can evade the immune system and have different genetic mutations compared to normal cells.
boy stop
You start to feel him and you suddenly stop being scared of things. You stop doing some of your old ways and do new and better things. You will know when it gets stronger. I personal start to cry.
