Designing Deletion Mutation Operators
One-op mutation is the idea of using a single powerful mutation operator that leads to a highly effective test set with a low cost SDL-mutation [15] is a one-op mutation version that uses Statement Deletion (SDL) Results showed that SDL-mutation yields huge savings in the cost of mutation testing without a significant loss of effectiveness [14]
Manipulating the Yeast Genome: Deletion, Mutation and Tagging
can be left in the strain so the mutation can be easily tracked, however a variation of this method involves excision of the marker so that the only change in the strain is the mutation 7, 13, 27 Other methods that couple the creation of mutant alleles to allele integration into the chromosome have also been described 28, 29
Types of mutations
Mutation Rate per bp • 10-9 per base pair per cell division • This refers to mutations that are not repaired (i e they’re fixed) • Thus, there are at least six new base changes in each kid that were not present in either parent, but this is an underestimate as there’s more since they accumulate in the germ line stem cells as the
DELETION INSERTION FRAMESHIFT POINT MUTATION changes MISSENSE
Point mutation – silent mutation If there was no effect on the protein coded by the gene, then the amino acid sequence must have been the same as the original sequence Therefore the mutation must have been a point mutation resulting in a codon that encoded the same amino acid as the original amino acid
Today’s lecture
Nonsense mutation: changes an amino acid to a STOP codon, resulting in premature termination of translation Missense mutation: changes an amino acid to another amino acid This may or may not affect protein function, depending on whether the change is “conservative” or “nonconservative,” and what the amino acid actually does
Types of Mutations (Science 10)
POINT MUTATION: one base is substituted for another If a point mutation changes the amino acid, it’s called a MISSENSE MUTATION If a point mutation does not change the amino acid, it’s called a SILENT MUTATION If a point mutation changes the amino acid to a “STOP,” it’s called a NONSENSE MUTATION Instructions: Complete the boxes below
