A Ramble through the Cell: How Can We Clear Such a Complicated Trail?

Abstract

The arrangement of course information in a logical sequence for molecular life science (MLS) courses remains a matter of some controversy, even within a single subdiscipline such as biochemistry. This is due to the explosion of knowledge, the latest bioinformatic revelations, and the observation that new discoveries sometimes reveal specific connections between previously disparate topics. However, the general outlines of biomedical information are in place, at least the knowledge that should be conveyed to undergraduates taking cell and molecular biology and biochemistry. Despite the increasing amount and complexity of the information to be presented, integration and unification are possible because the molecular reactions and interactions that underlie all life processes are coming into view: they are common to all cellular structural rearrangements, nucleic acid functions, and biochemical reactions, whether of plant or animal origin. Also, it is no longer possible to draw clear boundaries between cell biology, biochemistry, and molecular biology that would not violate the fundamental unity of our understanding. Therefore, an arrangement of content is proposed for a two-semester course that aims to present a unified portrait of upper-division undergraduate MLS.
