Answer 1

A mutation that involves a single nucleotide is called a point mutation. Point mutations can be silent, missense, or nonsense mutations and their effects depend on how they change the genetic code.

Step-by-step explanation:

A mutation that involves a single nucleotide is called a point mutation. Point mutations are changes in a single base pair of DNA and can be silent, missense, or nonsense mutations. An example of a point mutation is when the codon UUU is changed to UCU. Point mutations can have different effects depending on how they change the genetic code.
