Missense Mutation — Definition & Examples

By Gabi Slizewska
An amino acid chart. Non-polar amino acids include alanine, valine, methionine, leucine, isoleucine, proline, tryptophan, and phenylalanine. Basic amino acids include lysine, arginine, and histidine. Acidic amino acids include glutamic acid and aspartic acid. Polar amino acids include tyrosine, threonine, glutamine, glycine, serine, cysteine, and asparagine.

The damage from a missense mutation depends largely on the chemical properties of the amino acids that get swapped. Which of the following would most likely cause the least severe mutation if it replaced asparagine?
