Hank Greene Question set 7 1. Since it takes 3 bases to make a codon, which synthesizes an amino acid, than there must be a multiple of 3 bases in every gene. To know how many bases would be in a gene, you’d need to know how many amino acids the gene is responsible for, then divide that number by 3 that’s how many bases the gene has. 2. substitutions- when one nucleotide pair gets replaced by another pair of nucleotides. Insertions- when a nucleotide is added in a gene. Deletions- when a pair of nucleotides is deleted in a gene. External forces, such as x-rays, can also

Unformatted text preview: mutate a gene by joining two bases of thymine together, which damages the gene. 3. this would be a missense mutation, since one of the bases got switched around but the codon still codes for glutamine. 4. important mutations will affect the part of the peptide chain that is responsible for the structure of the enzyme, such as a chaperone protein. A genetic mutation could alter the primary structure, and primary structure determines conformation. This could cause the enzyme to not function at all....
