MICR 2123 Final Exam Questions with Answers All Updated Nonsense Mutation - Answer-The changed codon now calls for a stop codon, ending the genetic code early. Framshift Mutation - Answer-Most extreme type of mutation. A single base is added or deleted, changing the entire frame after the mistake. Control of Gene Expression: DNA Level - Answer-Most drastic and least reversible. Mutate the gene. Control of Gene Expression: Transcription Level - Answer-Activators and repressors, as we...

BIO 100 EXAM 2 STUDY GUIDE LATEST UPDATE GRADED A+ What characteristic of DNA evidence makes it particularly valuable in criminal investigations? Its uniqueness to each individual organism. What ensures the stability of the complementary base pairs in a DNA molecule? Hydrogen bonds. Why did the double helix model of DNA generate excitement in the scientific community? It elucidated how genetic material could be duplicated through complementary strands. What are the alternative ...

The spectrum of p53 mutations is not a strong argument to infer neomorphic or antimorphic mutations Unlike most other tumour suppressor genes that are inactivated by frameshift or nonsense mutations leading to disappearance or aberrant synthesis of the gene product, almost 80% of p53 gene mutations are missense mutations leading to the synthesis of a stable protein, lacking its specific DNA-binding activity and accumulating in the nucleus of tumour cells (Soussi, 2005). Whether this hig...
