Mutations involving many base pairs Deletions: mutations in which a region of the dna has been eliminated Insertions occur when new bases are added to the dNA, can be a sing de base or many bases(called insertion sequences) Translocation: large section of chromosomal dna is moved to a new locationMutations involving many base pairs • Deletions: mutations in which a region of the DNA has been eliminated • Insertions: occur when new bases are added to the DNA, can be a single base or many bases (called insertion sequences) • Translocation: large section of chromosomal DNA is moved to a new location
