QUESTION 3 In a "frameshift" mutation O a the mutation is not in DNA. the nucleotide that mutates causes a stop codon to occur instead of the placement of an amino acid. c. addition or deletion of one or two nucleotides causes the codons to be off pattern and therefore the mutation. 4. the nucleotide that mutates causes no change in the amino acid specified.

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....

10. Examine more closely how DNA changes in a co questions. Write the codon for the DNA sequence ATA then change only one nucleotide so that it codes for an RNA codon that is a STOP codon. If a codon changes to cause an mRNA to have a STOP codon instead of a codon for an amino acid, what type of protein mutation is this? Write the RNA codon(s) for histidine then change the last letter to a "G." What...
