MCAT Organic ChemistryWhat are the four rules for writing resonance structures? - correct answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? - correct answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple b...

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, ...
