EOC Genetics , Biotech, Mutations

A mutation is defined as:

• A change in the cell's structure

• Anything that changes in an embryo

• Any change in the physical features of a human

• A change in the DNA sequence

Why are insertion and deletion (frameshift) 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.

The survival of a species depends on its ability to adapt to changes in the environment. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?

• Mutations are a source of variation in the species

• Mutations are the cause of disease in the species

• Mutations are not harmful when they occur in somatic cells

• Mutations are always passed on to subsequent generations
