Same-Handed Molecules Are an “Overarching Design Principle” in Life, Say Researchers
Without foresight to solve heterochiral incidents, a primordial cell would quickly perish even if, against all odds, it began homochiral.
New Animation on Topoisomerase Demonstrates Irrationality of Denying Design Evidence in Biology
Replication or transcription of DNA stresses the macromolecule, resulting in supercoiling. Topoisomerase II relieves the stress.
Long Story Short — Did Purely Natural Processes Produce Biopolymers?
Science provides a clear expectation of what natural processes produce, and what we observe in the biopolymers of life is dramatically unexpected.
More on James Tour’s Abiogenesis YouTube Series
Brian Miller discusses the Levinthal paradox of the interactome, the long odds of blind processes assembling the first cell, and the challenge of cell death.
James Tour Video Series on the Origin of Life — Properly Combining Building Blocks
Any progress toward life would be lost if a fully functional cell did not emerge within a reasonably short period of time.
