What type of SNP does not change the amino acid sequence of a protein?
Understand the Problem
The question is asking about types of single nucleotide polymorphisms (SNPs) and specifically which type does not alter the amino acid sequence of a protein. This points to knowledge of genetics and molecular biology.
Answer
Synonymous SNP
The type of SNP that does not change the amino acid sequence of a protein is a synonymous SNP.
Answer for screen readers
The type of SNP that does not change the amino acid sequence of a protein is a synonymous SNP.
More Information
Synonymous SNPs occur due to the redundancy in the genetic code, where different codons can code for the same amino acid. Thus, even if the DNA sequence is altered, the protein's amino acid sequence remains unchanged.
Tips
A common mistake is confusing synonymous SNPs with non-synonymous ones. Remember that synonymous changes do not affect the amino acid, while non-synonymous ones do.
