How is Biochemistry, Cell and Molecular Biology (BCMB) Different

from Biology or Chemistry?

 

Since our name includes the words 'chemistry' and 'biology', some find it confusing to distinguish between BCMB and these other disciplines.

The best way to understand what a field is like is to examine national expectations of graduates in those fields.

Many disciplines have professional organizations that guide these expected educational outcomes. For Biochemistry, Cell and Molecular Biology, our professional organization is the ASBMB (American Society of Biochemists and Molecular Biologists).

Further, many graduate schools use GRE scores to judge student undergraduate preparation for their respective subject areas. We can thus use GRE exams for.more guidance about defining the national expectations for persons graduating from corresponding undergraduate programs.

Below are the GRE content areas in Biology, BCMB and Chemistry: More information can be found at http://www.gre.org/subjtest.html

 

When you look at these materials, you will clearly see that
1. The topic areas are different. The biology graduate is expected to know more about organismal biology and ecology (constituting 2/3 of the exam). Conversely, the biochemistry molecular biology student is expected to know more about biochemistry (absent from Biology GRE), as well as more depth in cell and molecular biology. Though chemistry is an important part of learning the bcmb subjects, the subject areas in chemistry are totally different from bcmb.
 
2. The BCMB student uses chemistry and biology to inform their study of life process on the molecular level, but it has emerged into its own field that is distinct from its parent fields of biology and chemistry..
