WebB-DNA has two principal grooves, a wide major groove and a narrow minor groove. Many proteins interact in the space of the major groove, where they make sequence-specific contacts with the bases. In addition, a few proteins are known to make contacts via the minor groove. Several structural variants of DNA are known. WebMinor groove is the target of a large number of non-covalent binding agents. DNA binding with specific sequences, mostly AT, takes place by means of a combination of directed hydrogen bonding to base pair edges, van der Waals interactions with the minor groove walls and generalized electrostatic interactions. pre med vs pre physician assistant

In a dsDNA helix, the nucleic bases are located in an almost coplanar arrangement, which allows planar WebDNA major and minor grooves. The latter is a binding site for the Hoechst stain dye 33258. Twin helical strands form the DNA backbone. Another double helix may be found tracing the spaces, or grooves, between the strands. These voids are adjacent to the base pairs and may provide a binding site.
