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...
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...
Using these types of genetic changes: Base substitution, Transition, Transversion, Missense mutation, Nonsense mutation, Insertion, Deletion, Frameshift mutation Label these genetic changes (a-e). More than one answer may apply to each answer. a. GC->CG in the protein coding region on a gene. b. GC->TA in a GAA glutamate codon c. Loss of three bases GAA for a glutamate codon d. GC->CG in a tRNA gene e. GC->AT in the ribosome binding site of a mRNA
Which type of mutation is likely to be more harmful? Substitution O Frameshift O Silent mutation Missense Point mutation What is the coding portion of a gene called? O Exon O Transcript Intron mRNA Okasaki fragment
