Learn how restriction enzymes recognize and cut specific DNA sequences to protect cells and support biotechnology.

Learn why thermal energy naturally flows from hot to cold regions and how particle motion and entropy drive the direction of heat transfer.

Learn what makes waves a powerful model for describing energy transfer and why oscillations allow energy to move without transporting matter.

Learn why oxidation and reduction always occur together and how electron transfer links the two processes in every redox reaction.

Learn why charges follow circular or helical paths in magnetic fields and how perpendicular magnetic forces shape their trajectories.

Learn how the laws of thermodynamics limit the efficiency of real engines and why no machine can convert heat into work with perfect effectiveness.

Learn why some molecules violate the octet rule and how electron availability, expanded valence shells and odd-electron species explain exceptions.

Learn why different cells express different genes and how gene regulation enables specialization and diverse cell functions.

Learn what interference fringes reveal about the nature of light and how they demonstrate its wave-like behavior through superposition and coherence.

Learn why atomic masses reflect weighted averages of isotopes and how natural abundance shapes the periodic table’s values.

Learn why electrons fill lower-energy orbitals before higher ones and how quantum principles shape orbital filling patterns.

Learn why some reactions release more energy than others and how bond strengths and stability determine reaction energetics.

Learn why hydrocarbons vary in structure and reactivity and how bonding, shape and saturation influence their chemical behavior.

Learn why Galilean transformations fail at speeds near light, and why classical assumptions break down when approaching relativistic motion.

Learn how PCR amplifies specific DNA sequences using primers, heat cycling, and DNA polymerase.

Learn how energy continuously shifts between kinetic and potential forms during simple harmonic motion, creating smooth, repeating oscillations.
