A wild type gene contains the DNA 3'CCG5' which would code for the amino acid glycine. A mutation changed the DNA to 3'TCG5' which would code for the amino acid serine. This is an example of which of the following?
Group of answer choices A silent mutation A missense mutation A nonsense mutation A frameshift mutation None of these

3. (1.8 points) The normal CFTR gene contains these six codons near the middle of the transcript: AUU UCU VUA GCA AGA GCU... Al The corresponding amino acids in the normal CFTR protein are: (Use either the one-or three-letter amino acid codes A naint mutation changes the last nucleotide from U to C. At the DNA level, this is a transition transversion c) At the protein level, this is a (silent / missense / nonsense/frameshift ) mutation. D) Instead of...

Helen has type I osteogenesis imperfecta (Oi), a genetic skeletal disorder. Shown below is her DNA sequence for a portion of the coding region of the collagen type I gene, which contains the mutation responsible for her disorder. The corresponding wild-type sequence is shown also (only one DNA strand is shown in each case). Helen Normal 5-AAACTCCACTTCTTCCAGTAC-3' 5'-AAACTCACTTCTTCCAGTAC-3' What type of mutation does Helen carry? frameshift-deletion frameshift-insertion nonsense silent missense

Match each type of mutation to the correct example. Nonsense mutation A codon in the PAH gene with a C-to-T mutation still specifies leucine. Silent mutation An allele of the CFTR gene where a codon mutated from AAG to TAG. Missense mutation A GGT (glycine) to GAT (aspartic acid) mutation in the KRAS gene A 2 base pair deletion in the ORF of the gene encoding the Retinitis Pigmentosum GTPase Regulator Frameshift mutation Promoter mutation A T-to-G mutation - 35...
