Match Column I with Column II

	Column I		Column II
a.	Missense mutation	i.	Changes a sense codon into a synonymous codon, leaving unchanged the amino acid sequence of the protein
b.	Nonsense mutation	ii.	Changes a sense codon into a different sense codon, resulting in the incorporation of a different amino acid in the protein
c.	Silent mutation	iii.	Changes a mutant phenotype back to the wild-type phenotype
d.	Reverse mutation	iv.	Changes a sense codon into a nonsense codon, causing premature termination of translation
