It also represents a first step to producing a formal structure in which overlap of bases is usually small. The following table gives the results of a survey where students were asked how they get to school.Ĭomplete the table and use your results to create a circle graph. What is a Circle Graph A circle graph is one way to display base pairs of a structure. Discuss your estimates with a classmate.Īre your estimates reasonable?
