Molecular biology is a branch of biology that studies living things at the molecular mechanisms underlying their physiology, focusing in particular on the interactions between macromolecules, ie proteins and nucleic acids (DNA and RNA). For molecular biology, it often means a number of techniques that allow the detection, analysis, manipulation, amplification (PCR) and copying (cloning) of nucleic acids.
