Applied DNA, RNA and 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

What are the building blocks of proteins called?

• DNA
• RNA
• Ribosomes
• Amino Acids

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.
