The dna molecule consists of two strands that form a double helix, a spiraling shape much like a twisted ladder the dna molecule has a sugar component, a phosphate component, and four different bases—adenine, thymine, cytosine, and guanine. History of dna research was working on a project in 1928 that formed the basis that dna was the molecule of inheritance griffith's experiment involved mice and two types of pneumonia – one . A 3-d dna model does not have to be difficult to build (image: simon999/flickrcom) a 3-d model of a strand of dna is an appropriate project for an elementary science fair that will even appeal to students more interested in the arts than in science while this may seem like a difficult project to .
The size of a double stranded dna molecule is measured by the number of base pairs it contains and a single strand is measured by the number of nucleotides it has as humans, we have a total of 6,000,000,000 base pairs in all of our chromosomes and the entire sequence of base pairs was published by the human genome project in 2003. How to make a model of dna using common materials making a model of dna is a great way to learn about how this magnificent structure builds our genes and determines our genetic makeup. Credit: udaix shutterstock deoxyribonucleic acid or dna is a molecule that contains the instructions an organism needs to develop, live and reproduce these instructions are found inside every .
