Molecular and cell biology has, in recent years, become an increasingly important aspect in all fields of biology, but especially in zoology. Studies on topics as diverse as conservation biology, taxonomy, evolution, physiology, developmental biology, and gene expression can all be studied at the cellular level. Most work at the molecular and cellular level requires specialised laboratories and equipment for extracting and working with DNA or proteins, although collecting material may involve trips into the field. Specialised training in molecular and cell techniques is usually gained at the postgraduate level and a good background in biochemistry, microbiology, genetics or molecular biology is strongly recommended.
Job opportunities for molecular and cell biologists are to be found in university departments or research institutions carrying out research in the zoological, agricultural and medical fields as well as in industries with a similar focus.
