What is the difference between a proto-oncogene and an oncogene? Group of answer choices 1. These are two categories of genes. Proto-oncogenes are genes that fight cancer, oncogenes are genes that cause cancer. 2. Proto-oncogenes are naturally occurring genes in the human genome, while oncogenes come from viruses that cause cancer. 3. These are alleles of the same gene. Proto-oncogenes are wildtype alleles, and oncogenes are cancer-causing alleles.

Retinoblastoma: The Hits Just Keep Coming 1.a There are three broad categories of cancer-related genes: proto-oncogenes, tumor suppressor genes, and DNA repair/stability genes. Distinguish between these three groups, then indicate which you think RB1 belongs to. b. In 1971, Alfred Knudson noticed that children like Kay, who have retinoblastoma in both eyes (bilateral), presented at earlier ages than those who had unilateral disease. To explain these different disease kinetics, he proposed the “two-hit hypothesis.” What does this hypothesis propose? c. Consider Dr. Whitt’s comments about the relationship between the wild-type and mutant RB1 alleles and what you now know about Knudson’s two-hit hypothesis. Do these ideas seem to confirm or contradict your earlier prediction (based on the pedigree) about whether the mutant RB1 allele is dominant or recessive to the wild-type allele? Explain. d. Do you think that Kay (and Julie) will be more likely to develop other cancers later in life?
Retinoblastoma: The Hits Just Keep Coming case study Part III – The Second Hit Questions A second hit might occur through epigenetic alterations. In the promoter of RB1, there is a CpG island. Knowing this, how might you predict that a cell could epigenetically inactivate RB1 transcription? A second hit might also occur through loss of heterozygosity (LOH). An example of how LOH may occur by reciprocal crossing over during mitosis is diagrammed in Figure 1 (next page). Discuss and interpret this model with your group. Write a brief explanation of (a) what LOH means and (b) how LOH by mitotic reciprocal crossing over can give rise to a cell lineage with functional loss of the wild-type copy of a tumor suppressor gene. . One of the ways that we know what the RB protein does in cells is that its inactivation is a common priority of tumor-initiating viruses. What advantage would a virus gain by inactivating RB function in its host cell? One example of a DNA virus (a virus that…
This is a blank question. Thank you in advance, Bloom Syndrome Bloom syndrome is a rare genetic disorder. It is characterized by short stature and a long narrow face with prominent nose and ears. There is also increased sensitivity to light. People who have the disorder often develop rashes on their face, forearms, and hands when they have been exposed to the sun. In addition, these people often suffer from chronic obstructive pulmonary disorder (COPD) and have a higher chance of developing cancer. The cause of this genetic disorder is a mutation in the BLM gene located on chromosome 15. The immediate effect of this mutation is that there is a defect in the functioning of the DNA helicase enzyme. What would be the effect of this mutation on DNA replication? What stage of the cell cycle would be most affected?
TRUE OR FALSE 1. Cancer cell lines may come from transformed cell lines. 2. Transgenic rats are rats that have foreign DNA inserted into their genome. 3. Passage number is the number of times the cell line has been used in cell assay.

THE MOLECULAR GENETICS OF CYSTIC FIBROSIS 2. What is the sequence of bases on the strand of DNA that is complementary to the template strand? 3. What mRNA will be formed from the template strand of DNA? The following is the base sequence of DNA that codes for amino acids 506-510 of the protein that regulates the chlorine channels in the cell membrane. This protein contains a total of 1476 amino acids so this is a small part of the entire gene. DNA Template Strand: TAGTAGAAACCACAA 1. What is the minimum number of DNA nucleotides in this whole gene? 4. What amino acids will this mRNA code for? 5. If the 6th, 7th and 8th bases in the template strand of the DNA are removed, rewrite the new template strand below. 1 6. When the template strand of the DNA is changed, this is referred to as a mutation. What kind of mutation is this? 7. What mRNA will be formed from the mutated template strand of DNA? 8. What amino acids will this new mRNA from the mutated template strand code for? 9. Are these…

I need help answering the following question from the following article https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2762880/ Science and Society: In 1966, Stanley Gartler presented his findings at an international conference- 18 of the most commonly used cell lines all contained the same genetic marker, G6PD-A. This gene allele is found almost exclusively in African Americans. This was a problem because a large number of these cell lines, excluding HeLa cells, were established from Caucasian individuals. He suggested that these lines were in fact contaminated with HeLa cells, which proliferate at extreme rates and were used in labs all over the world. What would you expect was the response of those scientists using the “contaminated” cell lines? Do you think this marker is enough to establish this contamination?

You are in charge of a new gene therapy clinic. Two cases have been referred to you for review and possible therapy. Case 1. A mutation in the promoter of a proto-oncogene causes the gene to make too much of its normal product, a receptor protein that promotes cell division. The uncontrolled cell division has caused cancer. Case 2. A mutation in an exon of a tumor-suppressor gene makes this gene nonfunctional. The product of this gene normally suppresses cell division. The mutant gene cannot suppress cell division, and this has led to cancer. What treatment options can you suggest for each case?
