Nonsense mutation - Study guides, Class notes & Summaries

what can restore a frameshift mutation? - another frameshift, microdeletion, and microinsertion A mutation in a particular gene that results in the premature halting of transcription (and, consequently, protein translation) is a___________ mutation. - nonsense Consider a mutation in which the change is from UAC to UAU. Both codons specify the amino acid tyrosine. Which type of point mutation is this? - Silent mutation A ʺpoint mutationʺ refers to mutations involving - a substitution, dele...

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...
