A mutation is....

• The result of too much sun exposure

• Any change in the DNA of an organism, can be inherited or acquired

• Caused by cancerous cells in the body copying too quickly

NGSS.HS-LS3-1

NGSS.HS-LS3-2

Produce changes in whole chromosomes

• Gene Mutation

• Mutagens

• Chromosomal Mutation

• Translocation Mutations

These mutations do not have an observable effect on the organism's phenotype

• Gene Mutation

• Silent Mutation

• Chromosomal Mutation

• Nondisjunction

Mutagens are....

• Environmental factors that cause mutations

• Gene mutations- piece of gene is added or breaks off

• Any change in the DNA of an organism, can be inherited or acquired

Gene mutation- piece of gene is added or breaks off which shifts the entire reading frame

• Inversion Mutation

• Insertion/Deletion/Frameshift Mutation

• Substitution Mutation

• Translocation Mutations
