Question

Identify the types of point mutations depicted. leucine (c t a) is transformed to valine (g t a). leucine valine missense mutation nonsense mutation silent mutation glycine (g g a). glycine glycine missense mutation nonsense mutation silent mutation lysine (a a g) is transformed to stop codon (t a g). lysine stop missense mutation nonsense mutation silent mutation.

a) Missense mutation
b) Nonsense mutation
c) Silent mutation
d) Frameshift mutation

Answer 1

The types of point mutations depicted are missense mutation, nonsense mutation, and silent mutation.

Step-by-step explanation:

The type of point mutations depicted in the given sequence are:

1. Missense mutation: leucine (CTA) is transformed to valine (GTA). This mutation changes the codon for an amino acid to a different codon, resulting in the substitution of one amino acid for another.
2. Nonsense mutation: lysine (AAG) is transformed to a stop codon (TAG). This mutation changes the codon for an amino acid to a stop codon, leading to premature termination of protein synthesis.
3. Silent mutation: glycine (GGA) is transformed to glycine (GGA). This mutation does not change the amino acid encoded by the codon, resulting in no change in the protein.
