Which of the following are tRNA anti-codon sequences that are one mutation away from being nonsense...
QUESTION Which one of the following statements is correct? A Anonsense mutation changes a stop codon to an amino-acid coding codon B: A nonsense mutation changes an amino-acid codon to a stop codon C: A silent mutation changes the amino acid sequence of the polypeptide D. A missense is usually more severe than a nonsense mutation E A Silent mutation is usually more severe than a missense mutation QUESTIONS "In a plant in which 2n - 24. what is the...
Consider a mutation in which the codon CUU is changed to AUU. Which of the following statements is TRUE with respect to this codon change? options: The mutation is a nonsense mutation. The mutation is a transition mutation. One hydrophobic amino acid is replaced with another hydrophobic amino acid. The mutation is suppressor mutation.
1. A mutation creates a STOP codon where one was not before. Which of the following could NOT be the mutation that occurred? a. Deletion b. Insertion c. Missense d. Nonsense E. Silent F. All of the mutations above could create a STOP codon where one was not before.
QUESTION 20 In a haploid, a nonsense suppressor su1 acts on mutation 1 but not on mutation 2 or 3 of gene P. An unlinked nonsense suppressor su2 works on P mutation 2 but not on 1 or 3. Explain this pattern of suppression in regard to the nature of the mutations and the suppressors. The mutations are likely frameshift mutations, resulting in three possible proteins. The suppressor mutation may be specifically complementing the protein shape of one mutant but...
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...
Which mutation would probably be the most deleterious? A missense mutation in the second codon A frame-shift mutation in the second codon A nonsense mutation in the last codon A silent mutation in the second codon A missense mutation in the last codon
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
Match each mutation with its appropriate description. A mutation that changes a codon that specifies an amino acid to a stop codon, resulting in premature termination of polypeptide synthesis. Silent mutation Frameshift mutation A mutation that results in a change in a codon such that a different amino acid is specified es Missense mutation A mutation that changes one codon to a different codon that specifies the same amino acid, such that there is no change in the resulting polypeptide....
A cell that is heterozygous for a nonsense mutation in a tumor suppressor gene would most likely: A) Group of answer choices B) grow but not divide C) have a normal cell cycle D) arrest and induce apoptosis E) have a slightly increased cell cycle and increased cell growth F) grow and divide uncontrollably Which of the following correctly describes an event that occurs during transcription: Group of answer choices A) A DNA molecule is chemically modified to become a...

Which mutations can a a nonsense mutation introducing a premature stop codon into a gene on chromosome 5 a single nucleotide substitution in which T replaces G on chromosome 2 a deletion of half of the long arm of chromosome 20 the long arms from two homologous chromosomes undergo a translocation an inversion of the short arm of chromosome 18
