Percentage of C and T that expect in sea urchin DNA has to be predicted. Concept Introduction: Base pairing in DNA: The two strands of the DNA double helix run in the opposite directions- one in 5’ to 3’ direction and other from 3’ to 5’ direction. The hydrogen bonding between two strands enhances the stability of the DNA; where the alignment of hydrophobic nitrogenous bases in the interior and hydrophilic phosphate and sugar groups on the exterior also enhance the stability. Adenine and thymine gives a pair forming two hydrogen bonds and cytosine and guanine gives rise to another pair forming three hydrogen bonds. Chargaff’s rule: The amount of adenine and thymine were always equal, and the amount of cytosine and guanine are always equal (A=T and G=C). The proportions of each (A/T: G/C) vary from one species to another.

The DNA from sea urchins contains about 32% A and about 18% G. What percentages of T and C would you expect in sea urchin DNA? Explain.

In a DNA Double helix ,why doesn't an A or T form two hydrogen bonds(out of the three possible) with G or C? Explain in detail.

Why does DNA with a high A-T content have a lower melting temperature, Tm, than DNA with a high G-C content?
