Question
GENE MUTATIONS
(1 short simple sentence each)
1) A scientist discovered a mutation in a particular gene. However, the mutation did not change the protein production from the gene sequence. What type of gene mutation (insertion, deletion, or substitution) most likely occurred? Explain the answer.
2) List 3 amino acids that have more then 1 codon
3) list 2 amino acids that have only 1 codon
4) The DNA sequence of a particular gene is 90 nucleotides long. If the 31st nucleotide is deleted, how many amino acids would the mutation likely impact in the gene? Explain the answer.

5)original DNA sequence: AAT TAA CCG CCC
Mutated DNA sequence: AAT TAA CCA CCC
1) is the mutation and insertion, deletion, or substitution.
2)Is the mutation classified as a point or frameshift mutation?
6)original DNA sequence: AAA TTC CCG GGG
Mutated DNA sequence: AAA TTG CCC GGG
1) is the mutation and insertion, deletion, or substitution.
2)Is the mutation classified as a point or frameshift mutation?
7)original DNA sequence:TTT CCC GGC TTC
Mutated DNA sequence: TTC CCG GCT TCA
1) is the mutation and insertion, deletion, or substitution.
2)Is the mutation classified as a point or frameshift mutation?

1) The mutation is a substitution because it did not change protein production, indicating that the amino acid encoded remained the same.
2) Three amino acids that have more than one codon are: leucine (Leu), serine (Ser), and arginine (Arg).
3) Two amino acids that have only one codon are: methionine (Met) and tryptophan (Trp).
4) The mutation would likely impact 10 amino acids in the gene because the deletion of one nucleotide shifts the reading frame, affecting all subsequent codons from that point onward.
5)
1) The mutation is a substitution because the DNA sequence has changed one base (CCA instead of CCG).
2) The mutation is classified as a point mutation because only one nucleotide is altered.
6)
1) The mutation is a substitution because the DNA sequence has changed one base pair (TTG instead of TTC).
2) The mutation is classified as a point mutation because it involves a single nucleotide change.
7)
1) The mutation is a substitution because there is a change in one nucleotide (GGC to GCT).
2) The mutation is classified as a point mutation because it involves a single nucleotide alteration.
