- - - - double helix
        
        chromosomes
        
        genome
        
        the complete complement of genetic
        material in an organism
        
        DNA associated with an array of
        different proteins into a complex struct
        
        The 2 strands are antiparallel
        One strand 5’ to 3’
        Other stand 3’ to 5’
        
        how is it formed
        
        The bases in opposite strands hydrogen-bond according to the AT/GC (chargoff's) rule
        
        by hydrogen bonds
        
        have major/minor groove
      - written:5' to 3'
        
        how is it formed
        
        Nucleotides are
        covalently bonded by Phosphodiester bond
        
        that links 2 sugars
        
        the backbone is formed from phosphates and sugars
        
        base to base by hydrogen bonds
- - - - five carbon sugar
        
        ribose
        RNA
        
        deoxyribose
        DNA
        
        sugar carbons are 1' to 5'
      - base:
        ring of carbon,nitrogen atoms
        
        bases
        
        DNA
        
        A,G,C,T
        
        RNA
        
        AGCU
        
        pairing
        
        Results consistently showed
        
        amount of adenine (A) = amount of thymine (T)
        
        amount of cytosine (C) = amount of guanine (G)
        
        attached to 1' carbon on sugar
      - phosphate
        
        attached to 5' carbon on sugar
