- Q2Which mutation would change the greatest number of amino acids in a protein?the substitution of a thymine nucleotide with a cytosine nucleotide near the beginning of a genethe addition of the nucleotides that make up an additional stop codon to the end of a genethe deletion of a single adenine nucleotide in the middle of a genethe insertion of a thymine, a guanine, and an adenine nucleotide in that order at the start of a gene30s
- Q3Mutations within the DNA sequence of an organism can —all of the aboveresult in alterations that are harmful to an organismresult in alterations that do not effect the organismresult in alterations that are helpful to an organism30s
- Q4A codon chart is shown below.Which of these changes to the DNA triplet 3’ GCT 5’ will affect the protein produced?GCATCTTCCGTT30s
- Q5A segment of DNA produces methionine, threonine, histidine, aspartate, and glycine when translated. A substitution mutation occurs and causes the synthesis of the segment as shown. Which is the new peptide chain when the new DNA segment is translated?Methionine, serine, histidine, aspartate, glycineMethionine, leucine, histidine, aspartate, glycineMethionine, proline, histidine, aspartate, glycineMethionine, phenylalanine, histidine, aspartate, glycine30s
