On the other hand it has been shown that chromosomal DNA may consist of a series of segments of replicons. For ordering them from smallest to largest, we identify each component and its function. Why do you think that carbohydrates are not digested in the stomach? The bases form pairs (base pairs); A with T and C with G. The base pairs connect with a sugar molecule and a phosphate molecule (making a nucleotide) that form a spiral staircase (double helix).
