Term
What type of mutations arise from point mutations that result in the formation or loss of a termination codon. The resulting protein maybe truncated (shorter) or "read through" (lose stop codon and makes it longer). |
|
Definition
|
|
Term
What type of mutation is generally much more serious and will cause a change all the way down a DNA sequence, making each codon (or every group of three bases) a different sequence, not just in one point or base like a point mutation, that would only slightly change the sequence of a single codon. A frameshift mutation happens not when a DNA base is simply changed, but when a whole base is added or deleted from the sequence of DNA. Causing the codon sets of 3 bases to be out of frame |
