Question
SCID in humans is associated with mutation in Hemoglobin Adenosine Diaminase p^53 ra following type of mutation in a proto - oncogene may cause cancer in human: Translocation of gene Gene amplification Point mutation within regulatory element. Point within gene All of the above The following statement is true about a tumor suppressor gene mutation to induce cell division of a mammalian cell: Proto-oncogene product must have decreased activity Tumor suppressor gene product must lose activity. Tumor suppressor gene product must have an increased activity. Proto-oncogene must lose ability to express mRNA Incidence of cancer in human increases with age suggesting that: Cancer is an infectious disease. Multiple mutations are required to develop cancer Cancer gene(s) cannot be acquired in lifetime. None of the above are Which of the is true concerning cancer cells? They do not exhibit density - dependent inhibition when growing in culture. When they stop dividing, they do so at random points in the cell cycle They are not subject to cell cycle controls. B and C only A, B, and C Posttranslational modification includes: Folding of protein by on chaperones Addition of carbohydrates on protein cleaving off some amino acids. Phosphorylation of protein All of the above.Explanation / Answer
ANSWERS :
33 . B. SCID (Severe Combined Immunodeficiency Disease) in humans is associated with mutatons in adenosine dianinase.ADA deficiency is systematic purine metabolic disorder that primarily effects lymphocyte development, viability, and function. SCID often diagnosed by age 6 months and usually by age 12 months.
34. E. All of the above.
35. C. Tumor suppressor gene product must have an increased activity.
36. B. Multiple mutations are required to develop cancer. The longer we live, more mutations we accumulate.
37. E.
38. E.
