DNA nucleotides and Semi conservative replication of DNA

This resource includes the basic structure of mononucleotides (deoxyribose linked to a phosphate and a base, including thymine, adenine, cytosine or guanine) and the structures of DNA (polynucleotide composed of mononucleotides linked by condensation reactions to form phosphodiester bonds) This resource also explains how complementary base pairing and the hydrogen bonding between two complementary strands are involved in the formation of the DNA double strand and help you to understand the process of DNA replication, and how Meselson and Stahl’s classic experiment provided new data that supported the accepted theory of replication of DNA.
