Classify each of the following into whether it represents a nonmutated proto-oncogene or a tumor suppressor gene. Proto-Oncogenes Tumor Supressor Genes Inhibitors of p53 Apoptosis is restrained Apoptosis is promoted Eventually become inactive Sufficient cyclin Inhibitors of cyclin Eventually become oncogenes Promoters of p53 Cell cycle is restrained Cell cycle occurs normally

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

Which of the following is a false statements about tumor suppressor genes? Gene amplification (duplication) of a tumor suppressor gene is less likely to result in cancer than gene amplification of a proto-onocogene. Individuals with a single normal copy of a tumor suppressor gene are more prone to cancer than those with two normal copies. Inactivation of tumor suppressor genes can lead to enhanced cell survival and cell proliferation. Epigenetic changes that silence tumor suppressor genes would not lead to...

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...

Question 24 5 pts 1. Beta-catenin is classified as a proto-oncogene and APC is classified as a tumor suppressor gene. Both are important parts of the Wnt signaling pathway. Describe the relationship between beta-catenin and APC. Explain in detail why they are classified as a proto-oncogene or tumor suppressor gene. 2. Suppose you're working in a cancer research lab and discover a small molecule...

1.) You are studying a particular type of cancer. You observe that the cells are expressing higher than normal levels of the activated version of the G protein Ras (ie, they contain more Ras-GTP than normal). a.(2 pts) Further study shows that the one of the Ras genes has been mutated, would you classify this as the mutation of a tumor-suppressor gene or an oncogene? b.(2 pts) Given your knowledge of the regulation of G proteins, suggest an explanation for...
