Secondary structure

In addition to its primary structure, DNA can be described in terms of its secondary structure.

The Secondary structure of DNA describes the parameters of the double stranded macromolecule as a whole.  See Image Gallery  (Images 1-4)



For B-DNA (Classic or Watson-Crick DNA) Secondary Structure  includes such features as:


                                 Strands: 

                                                    Antiparallel (one 5' to 3'; the other 3' to 5')

                                                    No irregular features

                                 

                                 Backbone:  

                                                    Smooth backbone line

                                                    Backbone on the outside, base-pairs on the inside                                 

                                                    Backbone on the outside, base-pairs on the inside  

                                Bases:                                            

                                                    Bases paired        (A-T,  G-C)

                                                    Base-pairs flat, planar                         

                                                    10 bases per turn

                                

                                Helix:                       

                                                   Right-handed helix (clockwise)
