• glucose

• cellulose

The monomer for nucleic acids is

• monosaccharide

• nucleotide

• amino acid

• fatty acid

The nucleotides in DNA pair together at the nitrogenous bases through hydrogen bonds(complementary base pairing) Which is the correct pairing of bases?

• Adenine and guanine; Cytosine and thymine

• Adenine and cytosine; Guanine and thymine
