Dna Structure Diagram Drawing. Watson and crick proposed that dna is made up of two strands that are twisted around each other to form a right handed helix. In really close on dna do you know what it would look like.
According to this model called as watson crick model the dna molecule is a double helix structure consisting of two long polynucleotide chains coiled round each other around an imaginary axis and running opposite to each other. The backbone of dna double helix is made by the sugar and phosphate molecules. Dna comprises a sugar phosphate backbone and the nucleotide bases guanine cytosine adenine and thymine.
Draw a diagram similar to the one below on the board note the angles between the phosphate sugar and base are important.
You can see it in its original context by following this link if you are interested. By applying this template you can design a professional looking dna structure diagram easily without any drawing skills with edraw science diagram template collection. As a result of the double helical nature of dna the molecule has two asymmetric grooves. Normally i prefer to draw my own diagrams but my drawing software isnt sophisticated enough to produce convincing twisted ribbons.
