In the context of organic chemistry reactions, what type of mutation changes a normal codon to a termination codon?
A
Frameshift mutation
B
Silent mutation
C
Missense mutation
D
Nonsense mutation
Verified step by step guidance1
Understand the concept of a codon: A codon is a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule.
Learn about the types of mutations: Mutations are changes in the nucleotide sequence of the genetic material. They can be classified into different types based on their effects on the protein sequence.
Identify the nonsense mutation: A nonsense mutation is a type of mutation where a normal codon is changed to a stop codon, leading to the premature termination of protein synthesis.
Differentiate between mutation types: Frameshift mutations involve insertions or deletions that change the reading frame, silent mutations do not change the amino acid sequence, and missense mutations result in a different amino acid.
Conclude that a nonsense mutation is the type that changes a normal codon to a termination codon, effectively stopping protein synthesis prematurely.
