Elusive cancer-related protein captured in flight

Scientists have for the first time seen how the MYC protein, which plays a central role in cancer, binds to a key protein and controls important functions in the cell. The study, published in Nature Structural and Molecular ...

Re-cracking the genetic code

Crack open a biology textbook and you will find the table summarizing the standard genetic code. This refers to the set of rules by which the cell "decodes" the information contained in DNA and "translates" it into the amino ...

Molecular biology

Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Writing in Nature, William Astbury described molecular biology as:

"[...]not so much a technique as an approach, an approach from the viewpoint of the so-called basic sciences with the leading idea of searching below the large-scale manifestations of classical biology for the corresponding molecular plan. It is concerned particularly with the forms of biological molecules and[...]is predominantly three-dimensional and structural—which does not mean, however, that it is merely a refinement of morphology. It must at the same time inquire into genesis and function."
