  4. Molecular Biology of the Cell (7th ed.) - Bruce Alberts, Alexander Johnson, Julian Lewis, David Morgan, Martin Raff, Keith Roberts, Peter Walter - W.W. Norton - Alberts pioneered the schematic, simplified molecular-cartoon convention for depicting proteins, nucleic acids, and macromolecular complexes, an approach so widely copied it now defines how textbooks visualize structure-function relationships.

  5. Campbell Biology (12th ed.) - Lisa Urry, Michael Cain, Steven Wasserman, Peter Minorsky, Jane Reece (originated by Neil Campbell) - Pearson - Neil Campbell pioneered the "Figure Walkthrough" and inquiry-based figure caption, prompting students to predict a macromolecule's function from its structure before revealing the answer, an interactive-reading device widely adopted by later texts.
