WebDNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These … Webstructure is known as B-DNA, and represents an average conformation of DNA, based on fibre diffraction studies. However, this average shape of DNA is very unlikely to exist within the cells of living organisms, for several reasons. First, there is simply not enough room for the DNA to be stretched out in a perfect, linear B-DNA conformation.
