Molecular biologists study biology at the molecular level. Molecular biology is a field of biology that deals with the biochemical processes within living cells such as DNA, RNA, protein biosynthesis and genetic coding. Even though considered a distinct discipline, molecular biology overlaps with other scientific fields like biology and chemistry; several techniques and concepts of genetics and biochemistry are applicable to this science as well. Molecular biologists have in-depth knowledge of cell physiology, genetics and biochemistry which help them in analyzing the cell processes and codes in living organisms, including human beings. They use sophisticated equipment like DNA synthesizers, cloning kits, electron guns and temperature cyclers. They study the molecular basis of genetic variations, heredity and gene expressions to determine how some biological traits are passed on from generation to generation. By analyzing the cellular makeup of bacteria and viruses, they help doctors in understanding how these microorganisms cause diseases, and how they can be treated. Molecular biologists work primarily in laboratories and may be employed in hospitals, pharmaceutical companies, biotech companies, colleges, environmental organizations, etc. to name a few.
