Unraveling DNA with Rational Tangles

The video introduces rational tangles, a mathematical concept first defined by John Conway, and explores their application in understanding DNA. It explains how rational tangles are formed using horizontal and vertical twists, which correspond to rational numbers through continued fractions. The video also discusses the equivalence of rational tangles and their unique properties. Additionally, it highlights the role of rational tangles in biology, particularly in DNA replication and cell division, and touches on current research and applications in various fields.
