Nope, that’s not it. Mutations • Change in genetic material • Some have little effect on gene expression or protein function. • Some have a large effect. • Some mutations may cause cancers or genetic disorders. • Some mutations might be helpful in different or changing environments. (Lead to evolution/natural selection) Types of Mutations •Point Mutation – changes in one or a few nucleotides. Impacts only one gene. •Chromosomal Mutation – changes in number or structure of entire chromosome Examples of Point Mutations Deletion Substitution Insertion Stated Clearly - Point Mutations Examples of Point Mutations Substitution • Change of one base to another. • Usually only changes one amino acid in final protein. Insertion •Addition of 1 or more bases in nucleotide sequence. •Causes frameshift Deletion • Removal of 1 or more bases. • Causes frameshift Types of Mutations The, Dog, Car, Arm, Red… Mutations - The Science of Survival
