Notice how the codon AAU codes for ASN. What would happen if a DNA mutation changed the RNA codon to AAC? Nothing changes, because AAC also codes for ASN. Mutations that DO NOT change amino acid sequences are called SILENT MUTATIONS.
DNA holds the code The code determines the amino acid sequence. The sequence determines the protein’s shape. The shape determines the function. What if a code change DOES change the amino acid sequence?
DNA mutation Change of RNA Different amino acids Altered protein or enzyme
Mutations that change enzymes or proteins are usually bad and often lethal tay sachs vid@ 15 min
Which mutation in a fruit fly could be passed on to its offspring? (1) a mutation in a cell of an eye that changes the color of the eye (2) a mutation in a leg cell that causes the leg to be shorter (3) a mutation in a sperm cell that changes the shape of the wing (4) a mutation in a cell of the digestive tract that produces a different enzyme
