WebThis model for the DNA structure was widely accepted and is known as Watson and Crick's model of DNA. The three dimensional (3-D) double helix model of DNA as proposed by Watson and Crick including the latest advances in its structure is described below: DNA is a two-stranded molecule. It is made of two helical chains or strands that … 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.
