Consider a mutation in which the change is from uac to uau. both codons specify the amino acid tyrosine. which type of point mutation is this?

The correct answer is: silent mutation

There are a few types of genetic mutation that can change genetic code. Those mutations can be classified:

1.Substitution-only one base is changed

•Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon

•Missense mutations-when one nucleotide is substituted and a different codon is formed

•Silent mutations-when a nucleotide is substituted and the same amino acid is produced

2.Insertion- extra base pairs are inserted

3.Deletion- section of DNA is deleted

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
