- (a) How does the duplication of individual genes occur? (b) individual that inherit a genetic condition known as xeroderma pigmentosum exhibit an extreme sensitivity to sunlight exposure and often develop skin cancer by the age of 10. What repair pathway is most likely disrupted as a result of such mutation? Explain why?A disease "D" is caused by a combination of genetic and environmental factors. Polymorphisms in multiple genes can make an individual susceptible to this disease. Can gene therapy be a feasible therapeutic option to treat "D"? Why or why not?When an invasive cancer occurs? A. When genetic mutation occurs in a cell B. Cells are abnormal and tumor are still in contained within its tissue of origin C. When cell's descendants mutated and divide excessively and look abnormal. D. When some cells have additional mutations and allow tumors to invade other tissues through circulatory system As a doctor, you observed that patient X has speech delay and taller than the normal person.

- Discuss Concepts Many human diseases are caused by recessive alleles that are not expressed in heterozygotes. Some people think that eugenicsthe selective breeding of humans to eliminate undesirable genetic traitsprovides a way for us to rid our populations of such harmful alleles. Explain why eugenics cannot eliminate such genetic traits from human populations.Can you explain the following? about the disease process of lung cancer Cigarette use, exposure to carcinogens, such as tobacco smoke, also in environmental pollutants, such as asbestos, radon, and industrial chemicals, or genetic predisposition. Induces genetic mutation in the DNA of lung cells, leading to initiation of the cancerous process. Expansion of mutated cells. Mutated cells begin to grow and divide uncontrollably forming abnormal cells known as tumors. Tumors can be classified as small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC). Tumor invades nearby tissues (Lung tissue, blood vessels, and lymph nodes.) Cause structural damage. Cancer cells break away from the primary tumor and travel through bloodstream or lymphatic system to the parts of the body. (Common sites of metastasis liver, bones, brain and lung tissues. Tumor stimulates the formation of new blood vessels to supply it with nutrients and oxygen, supporting its continued growth. Cancer cells can…A-In relation to Cystic Fibrosis (CF), you learned in some topics throughout the course that there are some treatment approaches/options for CF which utilise biotechnology concepts.

- 1. A patient has a mutated BRCA2 gene and a normal BRCA1 gene. Select the TWO answers that are correct. The patient has an increased risk of developing ovarian or breast cancer than a patient with normal BRCA1 and BRCA2 genes. The patient has a lesser risk of developing ovarian or breast cancer than a patient with normal BRCA1 and BRCA2 genes. The patient has a lesser risk of developing ovarian or breast cancer than a patient with a normal BRCA2 gene and a mutated BRCA1 gene. The patient has a greater risk of developing ovarian cancer and a lesser risk of developing breast cancer than a patient with normal BRCA1 and BRCA2 genes. The patient has a greater risk of developing breast cancer and a lesser risk of developing ovarian cancer than a patient with normal BRCA1 and BRCA2 genes.Skin cancer carries a lifetime risk nearly equal to that of allother cancers combined. Following is a graph [modified fromK. H. Kraemer (1997). Proc. Natl. Acad. Sci. (USA) 94:11–14]depicting the age of onset of skin cancers in patients with orwithout XP, where the cumulative percentage of skin cancer is plotted against age. The non-XP curve is based on 29,757 cancerssurveyed by the National Cancer Institute, and the curverepresenting those with XP is based on 63 skin cancers from theXeroderma Pigmentosum Registry.2.2.
