ification: DNA replication copies the entire DNA for cell division; protein synthesis involves transcribing and translating specific genes into proteins. Practice Exercises and Answer Keys To reinforce understandin
Nuclear Reactions Understanding nuclear reactions requires familiarity with several core ideas: Mass-Energy Equivalence: Expressed by Einstein's equation \(E=mc^2\), it explains how mass can be converted into energy during nuclear processes. Mass Defect: The difference between the mass of a nucleus
a particles, and gamma rays. Types of Nuclear Radiation Alpha Particles (α): Consist of two protons and two neutrons. They have a positive charge and are relatively heavy. Alpha particles have low penetration power and can be stop
ntum Chromodynamics (QCD): The modern fundamental theory of strong interactions describes quarks and gluons; however, its direct application to nuclear force is complex. Instead, effective theories and models are employed at the nucleon level. Characte
