Molecular and cell biologists study molecular aspects of various cellular structures and processes. Molecular and cell biologists can work on finding cures to various diseases by studying genes and how they mutate to cause diseases (such as cancer). Drug companies are always researching new products and molecular and cell biologists are a part of that research. They can work on developing therapeutic drugs to working on stem cell research and in many other areas within the medical development field. A molecular and cell biologist may find themselves working on research that involves cloning, sub cloning, synthetic RNA transcription, gene expression, cell growth and development, cell and organelle structure and assembly, and DNA dynamics and chromosome structure, and other types of laboratory work. Recording and analyzing various types of data is an important part of working as a molecular and cell biologist and will often be a part of one's job. Applying research to help solve health problems and to help cure diseases will also be an option for molecular and cell biologists.
