Silent mutation: If the base change results in the same amino acid being encoded, it is called a synonymous or silent mutation. This type of mutation does not alter the protein structure or function.
Missense mutation: A base change that results in a different amino acid being incorporated into the protein is called a missense mutation. This type of mutation can alter the structure and function of the protein, potentially impacting its activity, stability, or interactions with other molecules.
Nonsense mutation: A base change that introduces a stop codon (a codon that signals the end of protein synthesis) instead of an amino acid codon is called a nonsense mutation. This type of mutation results in the production of a truncated protein that may be non-functional or have reduced function.
Frameshift mutation: A base change that alters the reading frame of the gene, causing a shift in the grouping of codons, is called a frameshift mutation. This type of mutation can result in a completely different amino acid sequence and severely disrupt the protein structure and function.
The consequences of a base change on protein synthesis can range from minor alterations in protein function to complete loss of function or even harmful effects on the organism. Therefore, even a single base change can have significant impacts on the overall biological processes and phenotypes.
