- Explain how structural changes in genes on chromosomes may impact proteins and have negative, helpful, or neutral consequences on an organism's structure and function.In many genetic disorders, a lysosomal enzyme required to degrade a specific molecule is missing or defective. One example of these maladies, often referred to as lysosomal storage diseases, is Tay-Sachs disease. Afflicted individuals inherit a defective gene from each parent that codes for an enzyme that degrades a complex lipid molecule. Symptoms include severe mental retardation and death before the age of 5 years. What is the nature of the process that is destroying the patient's cells? (Hint: Synthesis of the lipid molecule continues at a normal rate.)Describe the relationships between each of the following: DNA, genes, transcription, translation and polypeptide (or protein).
- Xeroderma pigmentosum is an inherited disorder characterized by rapid formation of many skin sores that develop into cancers. All forms of radiation trigger these symptoms, including fluorescent light, which contains UV light in the range of 320 to 400 nm. In most affected individuals, at least one of nine particular proteins is missing or defective. What is the collective function of these proteins?When the state (e.g., growth rate, stage of cell cycle, differentiation, stress level) of a cell changes, do the proteins in the cell, or those secreted from the cell, change in a characteristic (fingerprint-like) pattern? Which proteins change, and how (relative amounts, modifications, splice forms, etc.)?Define Genome, Transcriptome, and Proteome. Include examples of each one and a very detailed description on their importance and functionality.
- Find non-cancerous, non--nonsense, point mutation genetic disease. Describe the disease's name and the type of mutation. Compare the gene sequence between wild type and mutant. Compare the polypeptide sequence and structure encoded by the wild type's gene and the mutant's gene. Describe and explain the consequences of the mutation to a patient's health. Note: 1. These questions will test the concepts of DNA-Protein transcription and translation on the effects of mutation. 2. Using dissimilar example/solution from your classmate and lecture's notes is encouraged. 3. Provide citation and reference.Explain how a mutation within a non-coding sequence may alter gene function.Each of the ff. involves a disorder in the function of an organelle or other cell structure. Identify the organelle or structure involved and indicate whether it is likely to be underactive or active. a) A maize plant is unable to survive due to recessive lethal gene which causes albinism. b) A baby is placed on a low phenylalanine diet as his newborn screening results revealed that he inherited phenylketonuria. c) A man develops pleiomorphic liposarcoma (rare cancer). The cause of the problem is a hard mass of cells in his right inner thigh that rapidly increased in size in a matter of 2 months. d) A girl suddenly felt weak and manifested cyanide poisoning symptoms after ingesting undercooked cassava which contains cyanoglycosides. e) A male chef learns that he is infertile because his sperm are non-motile.
