The synthesis of polypeptides by the Merrifield processes is much simpler than the synthesis polynucleotides for which of the following reasons: (Choose from the following four possibilities)

		Peptides are held together by amide bonds which are easier to form than phosphate bonds.
		Polynucleotides are less stable than peptides and this requires better control over the reaction conditions
		In peptide synthesis there are fewer groups to protect than in nucleotide synthesis
		The amine base components of the nucleotide often interfere with the coupling reactions and this lowers the yield.
