A certain mRNA strand has the following nucleotide sequence: 5AUGACGUAUAACUUU3 What is the anticodon for each codon? What is the amino acid sequence of the polypeptide? (Use Figure 13-5 to help answer this question.) Figure 13-5 The genetic code The genetic code specifies all possible combinations of the three bases that compose codons in mRNA. Of the 64 possible codons, 61 specify amino acids (see Figure 3-17 for an explanation of abbreviations). The codon AUG specifies the amino acid methionine and also signals the ribosome to initiate translation (start). Three codonsUAA, UGA, and UAGdo not specify amino acids; they terminate polypeptide synthesis (stop).
Which of the following describes a silent mutation that is undetectable in the final protein sequence? Group of answer choices A base change that codes for a chemically different amino acid A base change that results in a different codon for the same amino aci A base change that codes for a stop codon A base change that codes for a chemically similar amino acid
Which of the following types of mutation that changes the mRNA sequence after the codon that initiates translation is likely to have the most detrimental effect on the polypeptide product? Group of answer choices a substitution of the first nucleotide of a GGG codon a substitution of the third nucleotide in an ACC codon an insertion of a codon a deletion of two nucleotides a deletion of a codon
Finally, imagine that a mutation occurred in the codon below and an A was inserted between the two Ts. How would this affect the mRNA and the amino acid for that codon? Old DNA codon Old RNA codon Old amino acid New DNA codon New mRNA codon New amino acid T T G T A T G This would be an example of which type of a mutation?__________________________
What is a nonsense mutation? A change from a codon for one amino acid to a codon for another amino acid. A change in a degenerate codon position that doesn't change the meaning of the codon. A change from an amino acid codon to a stop codon. A change that adds or deletes a base from a codon. A change causing the protein to start in the wrong place.
