The tale proteins and the crispr/cas9 system are examples of molecular techniques used to perform in vivo DNA editing. Discovering the structures of biological molecules as well as their interactions and how these interactions explain findings of classical biology was how molecular biology was initially defined as an approach focusing on the underlying causes of biological events.
William Astbury, a physicist, coined the phrase "molecular biology" in 1945. In order to understand that a complex system or advantageous approach would be made in a straightforward manner of understanding, the field of molecular biological only recently developed. By using bacteria and bacteriophages.
