Gene Regulation and Mutation

Mutations increase the likelihood that a species will survive in a changing environment because they are a source of variation in the species.

NGSS.HS-LS4-2

DNA molecule segment is : TTA-CGC-AAG

The mutated DNA segment is TTC-GCA-AG. This is an example of ___ mutation.

• Substitution

• Deletion

• Insertion

• Inversion

Why are insertion and deletion mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence

• They insert things that an organism doesn't need.

• They often delete things that organisms need.

• Insertion and deletions are not any more harmful than substitution mutations.
