Original mRNA: AUG CCU GGA

Mutated mRNA: AUG CCC UGG

How was the protein affected?

Which statement is FALSE?

• DNA is double stranded and RNA is single stranded

• DNA is stuck in the nucleus and RNA can leave

• Both DNA and RNA are made up of nucleotides

• DNA has uracil and RNA has thymine

Not all mutations are harmful. What is a benefit of mutations?

• creates new disorders

• stops protein synthesis

• adds new genes

• produces codons for protein synthesis
