Figure 1: Comparing E-DNA with B-DNA and A-DNA. Figure 2: Electron density maps showing stereo views looking into the major grooves of the B-, E-, and A-DNA structures. The E-DNA crystal lattice has ...
IN the nucleic acids, cytosine is connected to a sugar residue through N 1 of the pyrimidine ring. Here we describe the results of an X-ray diffraction analysis of crystals of N 1-methyl cytosine. The ...
