how to make a dna structure model?
DNA is a double helical molecule composed of nucleotides, sugars and phosphate group. DNA structure model is first determined by Watson and Crick. The double helical structure of DNA consists of two strands that run parallel to each other linked by hydrogen bonds. Construction of Dna Structure Model Cut two pieces of craft wire of same length. Each craft wire of about six to eight inches long. Add white and black pony beads alternatively to the segment of craft wire. Make sure to start and finish with the same color pony beads on each craft wire strand. These color pony beads represents the sugar and phosphate group that makes up the backbone structure of the DNA structure model. Place the both finished craft wire strands next to (parallel) each other. Make a note of the number of colored pony beads pairs on each craft wire strands. This number is equal to the number of chemical base pairs which need to create. Cut the craft wire of two inch segments for making the chemical base pairs
