Explanation:
Cell cycle checkpoint controls play a major role in preventing the development of cancer [see Sherr, 1994, for a more detailed discussion]. Major checkpoints occur at the G1 to S phase transition and at the G2 to M phase transitions. Cancer is a genetic disease that arises from defects in growth-promoting oncogenes and growth-suppressing tumor suppressor genes. The p53 tumor suppressor protein plays a role in both the G1/S phase and G2/M phase checkpoints. The mechanism for this activity at the G1/S phase checkpoint is well understood, but its mechanism of action at the G2/M phase checkpoint remains to be elucidated. The p53 protein is thought to prevent chromosomal replication specifically during the cell cycle if DNA damage is present. In addition, p53 can induce a type of programmed cell death, or apoptosis, under certain circumstances. The general goal of p53 appears to be the prevention of cell propagation if mutations are present. The p53 protein acts as a transcription factor by binding to certain specific genes and regulating their expression. One of these, WAF1 or Cip1, is activated by p53 and is an essential downstream mediator of p53-dependent G1/S phase checkpoint control. The function of p53 can be suppressed by another gene, MDM2, which is overexpressed in certain tumorigenic mouse cells and binds to p53 protein, thus inhibiting its transcriptional activation function. Other cellular proteins have been found to bind to p53, but the significance of the associations is not completely understood in all cases. The large number of human cancers in which the p53 gene is altered makes this gene a good candidate for cancer screening approaches.

i don't know if this is right i tried
Not always,there are many people who are still in jail for crimes they did not commit,and some are free even though they commited crimes and were caught,but the judge said inocent
Answer:
Umm I think so because its to fast of an event that it goes away to quickly
Explanation:
The nucleic acids (specifically DNA and RNA) are the macromolecule that provides the blueprint for living things by storing and transmitting genetic information.
This is because the genetic information in our bodies is stored in our DNA (deoxyribonucleic acid) undergoes the processes of transcription (where it is transformed into mRNA) and translation (where the mRNA is translated into a polypeptide or protein). These two processes allow the information encoded in our genes to be expressed throughout our bodies through the usage of another macromolecule, the proteins.
Hope this helps!
