The evolution of pyrimidine bases
Evolution occurs when genes in a population of cells change in sequence and frequency over time and dominate by modification. However, in the evolutionary process, before the formation of cells, there must also be compounds that form these cells.

Angewandte Chemie, EarlyView.Um außergewöhnlich wirksame Wirkstoffe zu entwickeln, ist es erforderlich, über die Bindungsstelle hinaus zu denken. Diese Arbeit zeigt, dass die auf den ersten Blick kontraintuitive Adressierung einer konservierten Region der Kinase zu einer hochselektiven Bindung führen kann.

DNA Backbone Conformation in Cis-Syn Pyrimidine[ ]Pyrimidine Cyclobutane Dimers [PDF]
, 1980 A theoretical calculation involving minimization of energy functions was made to determine the conformation of a deoxydinucleoside monophosphate pyrimidine[ ]pyrimidine cis-syn cyclobutane dimer. Such single-stranded moieties are useful models for the in
