Concept explainers
Interpretation:
Charge of the DNA molecule as either neutrally charged, or positively charged, or negatively charged has to be predicted.
Concept Introduction:
Composition of
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 (complementary strand). 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, is present that enhance the stability too. Adenine and thymine gives a pair forming two hydrogen bonds and cytosine and guanine gives rise to another pair forming three hydrogen bonds.
