original: in the canonical watson-crick base pairing , adenine -lrb- a -rrb- forms a base pair with thymine -lrb- t -rrb- , as does guanine -lrb- g -rrb- with cytosine -lrb- c -rrb- in dna .
simplifications: in the canonical watson-crick dna base pairing , adenine -lrb- a -rrb- forms a base pair with thymine -lrb- t -rrb- and guanine -lrb- g -rrb- forms a base pair with cytosine -lrb- c -rrb- . in the canonical watson-crick dna pairing , adenine forms a base pair with thymine , and guanine with cytosine . in the canonical watson-crick base pairing , adenine forms a base pair with thymine as does guanine with cytosine in dna . in the -lrb- accepted / standard / simplest -rrb- watson-crick base pairing , adenine -lrb- a -rrb- forms a base pair with thymine -lrb- t -rrb- , as does guanine -lrb- g -rrb- with cytosine -lrb- c -rrb- in dna . in the canonical watson-crick base pairing , adenine froms a base pair with thymine , as does guanine with cytosine in dna . 1 . in the official watson-crick base pairing , adenine -lrb- a -rrb- forms a base pair with thymine -lrb- t -rrb- , as does guanine -lrb- g -rrb- with cytosine -lrb- c -rrb- in dna . adenine -lrb- a -rrb- forms a base pair with thymine -lrb- t -rrb- like guanine -lrb- g -rrb- with cytosine -lrb- c -rrb- in dna in the canonical watson-crick base pairing in the order by canon law , watson-crick base pairing , adenine -lrb- a -rrb- forms a base pair with thymine -lrb- t -rrb- , as does guanine -lrb- g -rrb- with cytosine -lrb- c -rrb- in dna .
