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....

11. Match each type of mutation with the corresponding description. (4 points) Missense An insertion or deletion of nucleotides that are not in multiples of 3. Nonsense A mutation that does not alter the protein sequence. Silent A mutation that confers an amino acid substitution. Frameshift A mutation that confers a premature stop codon.

1. In a "silent" mutation A) The codon that mutates does not cause a change in the amino acid specified B) The codon that mutates causes change in the amino acid specified C) The codon that mutates cause a stop codon to occur instead of the placement of an amino acid D) The mutation does not occur in a codon E) The mutation is not in DNA 2. In a "nonsense" mutation A) The codon that mutates does not cause...

D Question 4 A silent mutation has no change in RNA sequence O no change to DNA, RNA, or protein O no change in protein sequence O no change in DNA sequence Question 5 Which mutation changes one amino acid for another? nonsense all of these are correct missense silent
Consider a mutation in which the codon CUU is changed to AUU. Which of the following...
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.

A gene point mutation that converts the sequence of the codon and therefore converts the encoded amino acid to a stop codon: missense mutation frameshift mutation silent mutation nonsense mutation A mouse gene was identified and determined to be required for formation of heart muscle. A gene with a similar sequence was identified in the human genome. What experiment could scientists do to determine if the mouse and human genes have similar functions? The scientist could place the mutant mouse...

Dystrophin is a protein that forms part of a vital protein complex that connects the cytoskeleton of a muscle fiber cell to the extracellular matrix. This connection strengthens and shapes the muscle fibers. Dystrophin is coded by the DMD gene. This is one of the longest human genes known, covering 2,300,000 base pairs (0.08% of the human genome) It is located in chromosome 21. The immature mRNA is 2,100,000 bases long and takes 16 hours to transcribe. It contains 79...
