Watson and Crick’s Model of Double Helix of DNA Biochemistry

WebWatson and Crick proposed the molecular structure of DNA which they termed the “double helix”. The specific pairing of nucleotides is a key feature of the Watson and Crick model of DNA. Here, each DNA strand is linear and long, comprising smaller units known as nucleotides which in turn form a chain. WebJ.D.Watson and F.H.C.
