Question

A mutation occurs in a coding region of DNA, that is, in a gene. ONLY 1 nucleotide changes, but the amino acid sequence that is produced is unchanged. What type of mutation is this? Choose all that apply

Answer 1

Answer:

Point mutation

Explanation:

Point mutations affect a specific region of the DNA. If the codon affected is a non-coding(not coding for any amino acid example is the stop codon) base then the amino acid sequence will not be affected and if the base(codon) have substitution the amino acid sequence will remain unchanged.
