Purines - Study guides, Revision notes & Summaries

Purines and examples of them Purines contain two carbon-nitrogen rings and four nitrogen atoms. Adenine and guanine Pyrimidines and examples of them pyrimidines contain one carbon-nitrogen ring and two nitrogen atoms. Thymine and cytosine Structure of DNA DNA is a double helix (two helical strands.) The two strands are held together by the 'rungs', which are made of complementary pairs. The pairs are held together by weak hydrogen bonds. Arrangement of DNA antiparallel arrangement, ...
