Notes on dna
WebThe molecular structure of DNA comprises three components- a pentose sugar (deoxyribose for DNA), a phosphate group, and a nitrogenous base. Nitrogenous bases are of two types- Pyrimidines (uracil, thymine, cytosine) and Purines (guanine and adenine) The Double-helix structure of DNA is made from two polynucleotide chains. WebFigure 1. DNA has (a) a double helix structure and (b) phosphodiester bonds. The (c) major and minor grooves are binding sites for DNA binding proteins during processes such as transcription (the creation of RNA from a DNA template) and replication. At around the same time, three hypotheses for the modes of DNA replication were being considered ...
