If the DNA sequence $\mathrm{A}-\mathrm{T}-\mathrm{T}-\mathrm{G}-\mathrm{G}-\mathrm{C}-\mathrm{C}-\mathrm{T}-\mathrm{A}$ on an informa- tional strand mutated and became $\mathrm{A}-\mathrm{C}-\mathrm{T}-\mathrm{G}-\mathrm{G}-\mathrm{C}-\mathrm{C}-\mathrm{T}-\mathrm{A},$ what effect would the mutation have on the sequence of the protein produced?
A mutation that altered a single nucleotide within the anti-codon of a tRNA molecule could be expected to have which of the following consequences? The polypeptide amino acid sequence could be altered due to an incorrect amino acid bound to the mutant tRNA. This would be less likely to affect the amino acid sequence if the mutation occurred on nucleotide 1 or 2 of the anti-codon. The polypeptide amino acid sequence could be altered due to incorrect base-pairing between the mutant tRNA and mRNA codons. More than one option is possible.

Here is a hypothetical sequence of a template strand of a gene in the DNA of a hypothetical organism: 3' CGTACGGTAAGATTG 5' Suppose that the underlined "A" was mutated to a "G". What effect would this have on the amino acid sequence encoded by this gene?
