Diagram is missing in question but the correct answer is backbone.
- DNA constitutes of nitrogenous base, phosphate and sugar. It is made of two strands, that run antiparallel to each other.
- The coiled springs can be used as strands, to construct the model of DNA.
- DNA is made up of four nitrogenous bases namely Adenine, Thymine, Guanine and Cytosine.
- Each turn contains 10 base pairs and is 3.4 nm long.
