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.
Answer:
ribosome, cell membrane, nucleus
Explanation:
The organelles that perform similar functions in both plant and animal cells among the listed organelles would be <u>the ribosome</u>, <u>the cell membrane</u>, and <u>the nucleus.</u>
First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.
The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.
The simple answer is, ALWAYS have an evacuation plan.
If in an earthquake stay away from cabinets, climb under a table or chair, and do the right sitting position (Hold on to your neck position.)
Hope I helped, would love if you left me a thanks! Thanks :)
Answer:
Pyruvate kinase is the important enzyme that catalyzes the conversion of phosphoenol pyruvate into the pyruvate in the glycolysis cycle. This step generates the ATP molecule.
The regulation of the pyruvate kinase is done by the allosteric regulation and fructose 1,6 biphosphate activates the pyruvate kinase. This regulation is important as it control the metabolites present in different organs. The metabolites like fructose, galactose enters in the glycolysis from the liver after the particlar step of glycolysis.
Answer:
The mismatch pair is plasmodium causes chagas disease. Chagas disease occurs due to Trypanosoma cruzi.
Explanation:
Chagas disease is a parasitic disease .It also known as American Trypanosomiasis. Chagas disease is occurs due to the <u>Trypanosoma cruzi</u> parasite.It is spread mostly by insects .The name of the insect is Triatominae, or "kissing bugs". The symptoms change during the course of the infection.
Plasmodium is a protozoan parasite which causes malaria in the human body.
Giardia is a microscopic parasite. It has been contaminated with feces (poop) from infected humans or animals.So this match is correct.
African sleeping sickness caused by a microscopic parasite species <u>Trypanosoma</u> <u>bruce</u>i. It is transmitted by the tsetse fly , which is found only in rural Africa.
Histoplasmosis (Ohio valley fever) is a fungal infection which causes by Histoplasma .It generally effect on lungs and immune system.
Trichomoniasis (or “trich”) caused by infection with a protozoan parasite called<u> </u><u>Trichomonas</u> <u>vaginalis</u>.Its a sexually transmitted disease (STD).It cause foul smelling in women vagina.
