PROTEIN SYNTHESIS (From DNA to Protein)

What is the purpose of DNA?

• to aid in facilitated diffusion

• stores hereditary information

• reduces the activation energy

• manufactures proteins

The diagram displays the copying of a DNA sequence from a gene before and after the copy is made. The * represents an error that was made. Identify what this error is called.

• insertion

• deletion

• silent

• nonsense
