What is Molecular Biology?

* ''Biochemistry'' is the study of the chemical substances and vital processes occurring in living organisms. Biochemists focus heavily on the role, function, and structure of biomolecules. The study of the chemistry behind biological processes and the synthesis of biologically active molecules are examples of biochemistry.
* ''Genetics'' is the study of the effect of genetic differences on organisms. Often this can be inferred by the absence of a normal component (e.g. one gene). The study of "mutants" – organisms which lack one or more functional components with respect to the so-called "wild type" or normal phenotype. Genetic interactions (epistasis) can often confound simple interpretations of such "knock-out" studies.
* ''Molecular biology'' is the study of molecular underpinnings of the process of replication, transcription and translation of the genetic material. The central dogma of molecular biology where genetic material is transcribed into RNA and then translated into protein, despite being an oversimplified picture of molecular biology, still provides a good starting point for understanding the field. This picture, however, is undergoing revision in light of emerging novel roles for RNA.

A Tweak to the Figures - falsifying data and figures

"The Scientist notes that the papers that include the falsified figures, which appeared in Endocrinology and Molecular Endocrinology, are in the process of being retracted. Writedit also reports that a former Wyeth researcher, Boris Cheskis, has accepted to a two-year agreement after Office of Research Integrity found that he falsified figures submitted to NIH."
