Every person has these cell cycle proto-oncogenes, but not every person has cancer why might this be the case why might this be the case (3 points) a: these genes are in everyone and are just a normal part of the process until they end up mutating, causing cells to grow at a rate too fast for normal functions. A major class of oncogenes, the oncogenes present in acute transforming retroviruses, has homologues in animal genomes these cellular counterparts are called proto- oncogenes proto-oncogenes : proto-oncogenes participate in normal cell function, and in certain cases, a mutation or aberrant activation of a proto- oncogenes causes tumour formation. Other work has shown that her-2/neu overexpression to be associated with estrogen receptor negativity, poor tumor cell differentiation, and decreased patient survival6 it is clear that this proto-oncogene is important in the development of several forms of cancer but the story is far from complete. Cells work together to form organs, such as the heart, liver, and skin human bodies have several organ systems cancer begins when genes in a cell become abnormal and the cell starts to grow and divide out of control. Every person has these cell cycle proto-oncogenes, but not every person has cancer why might this be the case part iii—like mother, like daughter dr o'brien had handed judy a pamphlet on melanoma before he left the room as she started reading it, judy realized that this is what they were going to test her for.

Cancer cells have developed their own mechanisms that override the back-up systems of cells, ultimately leading to their proliferation another event occurs and this time the cell gains a mutation in a proto-oncogene this means that not only has the cell lost a suppressive regulatory mechanism, but now, proliferation is promoted. Every person has these cell cycle proto-oncogenes, but not every person has cancer why is this the case proto-oncogenes have to become mutant in order for cancer to occur, the proto-oncogenes are called oncogenes when mutant, and it usually requires more htan one for cancer to occur. With no functional p53, p21 is not activated and the cell cycle proceeds without any hindrance at all and this forms a platform for cancer cells to grow without being checked now mutations of the p53 gene are so common that the cluster of malignancies caused by p53 mutations has been given a name: lifraumeni syndrome. Every person has these cell cycle proto-oncogenes, but not everyone has cancer why might this be the case question 6 just sign into chegg tutors at the scheduled start time and visit your unique link lesson proposal submitted your lesson was successfully proposed we'll notify you as soon as a response is received from your tutor.

Research & development cell cycle in cancer the cell cycle, the process by which cells progress and divide, lies at the heart of cancer in normal cells, the cell cycle is controlled by a complex series of signaling pathways by which a cell grows, replicates its dna and divides. Module 02 case study: integumentary system module 02 case study: integumentary system every person has these cell cycle proto-oncogenes, but not every person has cancer why might this be the case (3 points) part iii—like mother, like daughter questions 1. The second type of cancer-causing gene is a tumor suppressor, whose normal function is to halt cell division just as a proto-oncogene has a normal function, so too does the unaltered version of a tumor suppressor gene and its encoded protein it shuts down cell division when it is no longer necessary. A few of these cell-cycle and proofreader genes are also known as oncogenes (cancer genes), because mutations in these genes are tied to the development of cancers if a gene that is supposed to tell a cell to stop growing stops working -- that is, mutates -- then the cell grows uncontrollably, dividing faster than it should.

Part 2 judy did a little research about skin cancer on the internet before her doctor's appointment the next every person has these cell cycle proto-oncogenes, but not every person has cancer why might this be the case. The cell cycle (or cell-division cycle) is a series of events that take place in a cell, leading to its division and duplication cell division requires cell cycle checkpoints (cps) that are used by the cell to both monitor and regulate the progress of the cell cycle. Every time a cell replicates its dna mistakes can occur about once every 10,000 to 100,000 times, dna polymerase, the enzyme responsible for adding nucleotides to a new strand of dna, will add the wrong nucleotide or add too many or too few bases in a specific location. Metastatic cancer has the same name and the same type of cancer cells as the original, or primary, cancer for example, breast cancer that spreads to and forms a metastatic tumor in the lung is metastatic breast cancer, not lung cancer.

Cancer-promoting oncogenes are typically activated in cancer cells, giving those cells new properties, such as hyperactive growth and division, protection against programmed cell death, loss of respect for normal tissue boundaries, and the ability to become established in diverse tissue environments. A specific damage would be a burn, any burn in which skin cells would have to replace the ones that were burned off or damaged 6 every person has these cell cycle proto-oncogenes, but not every person has cancer. Best answer: cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis (in which cancer cells are transported through the blood or lymphatic system. Unformatted text preview: every person has these cell cycle proto-oncogenes, but not every person has cancerwhy might this be the case (3 points) part iii—like mother, like daughter questons 1 now that you know a little more, what are the risk factors that increase a person's chances of having melanoma.

Every person has these cell cycle proto oncogenes but not every person has cancer why might this be

every person has these cell cycle proto oncogenes but not every person has cancer why might this be  The cycle is actioned by proteins controlled by proto-oncogenes cell division has a check  eggs and sperm consist of only half that number, 23 chromosomes per cell every person inherits one set of chromosomes from their mother (in the egg) and the other set of chromosomes from their father (in the sperm)  are responsible for the cancer.

Proto-oncogenes and tumor suppressor genes have the opposite effect of the division of cells proto-oncogenes, like explained earlier, is a mutation that accelerates the production of cells an example is a retrovirus called rsv. Oncogenes, the mutated forms of these proto-oncogenes, cause the proteins involved in these growth-promoting pathways to be overactive thus, the cell proliferates much faster than it would if the mutation had not occurred. This is why it is said that cancer is “a disease” related to age (with some exceptions), meaning that the older an individual is (not only humans, but also animals and plants), the more chances it has to have a cancer. Every person has these cell cycle proto-oncogenes, but not every person has cancer why might this be the case (3 points) every person has cell cycle proto-oncogenes and in normal, healthy oncogene cells they are what regulate cell growth and division when a person has a mutated form of the proto-oncogene the cell growth is not normal and.

Judy learned that every single person has these cell cycle genes so cells in our body can divide when necessary what are some normal circumstances where our bodies might need to make more cells why is the skin continuously replacing its main cell and what specific damages to the skin would there be a need to make more cells. Cancer cells, which have obviously sustained some form of damage that poses a threat to the rest of the organ, do not get the signal to commit suicide (programmed cell death) these cells do not go through the cycle of life that other normal cells go through. However, in cancer cells, the damaged dna is not repaired and the cell does not die like it should instead, the cell continues making new cells that the body does not need these cells all have the same abnormal dna as the first cell does. Every person has these cell cycle proto-nosecones, but not every person has cancer why might this be the case (3 points) we all have them because in normal, healthy cells they are what regulate cell growth and division.

Oncogenes and tumor suppressors—and the mutations that affect them—are different beasts from the point of view of the cancer gene hunter but from a cancer cell's point of view they are two sides of the same target.
