short answer questions
- A carcinoma is cancer that occurs in the skin or tissue cells that line the body’s internal organs, such as the kidneys and liver. Sarcoma is cancer that develops in the body’s connective tissue cells, which include fat, blood vessels, nerves, bones, muscles, deep skin tissues, and cartilage.
- difference between cancer and
normal cell
- uncontrolled proliferation
- undifferentiated
- escape from immune system
- evasion of cell death
- develops angiogenesis
- benign tumor is a mass of cancerous cells enclosed in a capsule and doesn't spread to distant parts whereas malignant cancer can metastasize from the origin to distant place or shows invasion.
- oncogenes are the mutated proto-oncogenes which help in cell proliferation whereas tumor suppressor genes will inhibit the proliferation of the cell. , Raf kinase and cyclin-dependent kinases. are oncogenes and BRCA1 and BRCA2are tumor suppressor genes
- because the finger-like spreading projections from a cancer called to mind the shape of a crab.

You are an oncologist (cancer doctor) who specializes in pioneering new advances in cancer therapies. You have been given an exciting new gene therapy treatment that aims at increasing the levels of the p53 protein in tumor cells that have lost all functional p53. You have a cancer patient who is going to be one of the first people ever to receive this treatment since their tumor cells have mutated versions of p53. But they have many questions about the...

13. Which of these statements is TRUE? a. Cancer cells usually have more than one mutation. . Proto-oncogenes are normal genes that code for proteins that cause cells to undergo apoptosis (programmed cell death) c. Cancer usually involves a gain-of-function mutation in a tumor suppressor gene d. Cancer usually involves a loss-of-function mutation proto-oncogene

1. Inflammation can play a role in cancer (development and/or progression) in which of the following ways? Select all that apply. Question options: A) TILs can secrete pro-inflammatory cytokines that promote cancer. B) TAMs can attack cancer cells and destroy them. C) Ulcerative colitis can progress to colon cancer. D) Immune cells associated with a cancer can secrete angiogenic and growth factors. E) Hepatitis C infection can lead to liver cancer. F) Hypercholesterolemia can develop into leukemia. 2.

There are two main types of cells in the human brain, neurons (nerve cells) and glial cells (supporting cells). Once neurons fully mature, these nerve cells no longer divide. Glial cells, however, continue to divide over a person’s entire lifetime. GDNF (glial cell line-derived neurotrophic factor) is a small protein that stimulates growth in glial cells. What kind of signal molecule is this protein? How does GDNF likely promote cell division? After the glial cell receives GDNF, what will happen...

The following list describes ways that CRISPR may be used to treat cancer. Which of the following describes immunotherapy instead of CRISPR therapy? Multiple Choice C ) Cytotoxic T cells may be stimulated, creating an immune response against cancer cells and shrinking tumors. Cancer causing mutations within cells may be corrected, preventing cancer from occurring Mutated proto-oncogenes may have their previous function restored, allowing normal regulation of cell division oooo Nucleotides within DNA may be removed, inactivating genes that are...

If S phase checkpoints detect nucleotides deficit, what happens to the dividing cell and the cell cycle? 3. What three conditions may be detected during the G2 checkpoints, and what are the two possible results if there is inadequate DNA or spindle fibers? 4. What two conditions are checked during the metaphase checkpoint? What happens if the cell “passes” the...
