Dna base pairing worksheet there are base pairing rules for writing complimentary dna strands for a given strand a pairs with t c pairs with g in rna. Dna contains two strands wrapped around each other in a helix, and these strands are held in place by four chemicals called bases: adenine (a), guanine (g), cytosine (c) and thymine (t) the bases pair up with each other in a specific manner to form units called base pairs - adenine always pairs with thymine, and cytosine always pairs with guanine. To understand nucleotide structure and base pairing nucleic acids are organic molecules that carry an organism's genetic information deoxyribonucleic acid (dna) and ribonucleic acid (rna) are examples dna and rna are composed of nucleotides, linked together to form long chains a nucleotide is.
