Structural biology is the study of the molecular structure and dynamics of biological macromolecules, particularly proteins and nucleic acids, and how alterations in their structures affect their ...

not nucleic acid, but by the late 1940s, DNA was largely accepted as the genetic molecule. Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked.

Can be used to recap on acids, alkalis and bases or could lead into a classroom discussion on chemical changes and structures.

Levene made his initial proposal in 1919, discrediting other suggestions that had been put forth about the structure of nucleic acids ... chemical components of the four bases and other nucleotide ...

Nucleic acids are complex biological molecules that store and transmit genetic ... In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G ...
