What is the difference between a mutation in a somatic cell and a gamete?
Genetic Changes (Mutations) • Terms • Mutation-a change in the DNA sequence • Most are bad, but not all • Mutagenic agent (Mutagen)-substance that causes a mutation • Radiation (UV), chemicals (tobacco)
Cell type and mutations • Somatic cell (any cell in body) • Cell may die • Cell may start to divide rapidly (cancer) • Gamete (sperm, egg) • Mutation will be passed to offspring • Every cell in offspring will have mutation • Can have a variety of effects Cancer
Types of Mutations • Point Mutation (Substitution) • One nucleotide is changed resulting in one amino acid change • ATG CTG GGA • ATG GTG GGA • Frameshift Mutation • One Nucleotide deleted or added, result in all amino acid changed • ATG CTG GGA • ATCTGG GA • Inversion • Section of DNA is flipped • ATG CTG GGA • ATTCGG GGA
