In studies of disease-discordant monozygotic twin pairs, one searches each pair for _____, focusing on those areas of DNA that are thought to be involved in the disorder. A. amino acid differences B. genetic differences C. epigenetic differences D. mutations

Step 1
Monozygotic twins share nearly identical DNA. Disease discordance means one twin has the disease and the other does not. Therefore, the differences between the twins must be investigated. Show more…

RFLPs, used in the search for the Huntington's Disease gene, can be used to identify point mutations through which of the following mechanisms? Group of answer choices a. The mutation can occur in a restriction site, causing a change in the cutting pattern for restriction enzymes. b. The mutation can be silent in the coding for protein, resulting in a different amino acid being inserted. c. The mutation can occur outside of a restriction site, causing a change in the cutting pattern for restriction enzymes. d. The mutation can occur, causing a shortening of the mRNA that is then compared to wild type. 2. SNPs are characterized by being ________. Group of answer choices a. highly heterogeneous with variable amino acid substitutions b. highly uniform in the population with variable numbers of tandem repeats c. variable in the population with variable base sequences d. homogeneous with various nucleotides transcribed repeatedly 3. The genomes of several hundred to several thousand diseased individuals are subject to individual genome sequencing as well as several thousand non-diseased individuals. The genomes are then compared to determine if there are patterns or associations between certain genes and the disease state. This does not mean a carrier of the correlated gene will develop the disease, just that there is a risk factor. This was done with age-related macular degeneration and is called: Group of answer choices a. Genome Wide Association Studies (GWAS) b. HapMap c. RFLP d. QTL

Which one of the following describes an epigenetic change? a. A mutation in a gene coding sequence that affects phenotype and can be inherited b. A mutation in a regulatory sequence that affects phenotype c. A histone modification that prevents expression of a gene, resulting in a phenotypic change that is inherited d. Disruption of a gene by a TE resulting in a phenotypic change Which reporter construct design would be best for monitoring where, when, and how much a gene-of-interest is transcribed? (GFP = green fluorescent protein) a. Replace the CRM with the GFP sequence and leave the promoter and gene coding region intact. b. Replace the promoter with the GFP sequence, leaving the CRM and gene coding region intact. c. Include the CRM and promoter but replace most of the gene coding region with the GFP sequence. d. Include the CRM and promoter and add the GFP sequence to the end of the gene coding region, in the same reading frame. Which of the following statements concerning the GC content of SARS-CoV-2 is TRUE? a. Various strains of SARS-CoV-2 have very different average GC content. b. The average GC content of the virus is higher than that of the human genome. c. The average GC content of the virus is lower than that of the human genome. d. The average GC content of the virus and the human genome is equal, suggesting long-term adaptation of the virus to its host.
