Exome: the part of the DNA that is transcribed into RNA and that remains after the RNA molecule undergoes liposuction. Well, not actual liposuction. DNA is like a book of blueprints, each blueprint being a gene; RNA represents a photocopy of a particular blueprint. The analogy, while useful, breaks down in the following way: the … Continue reading

Unveiling Culprits, Part 1: The Immunological Morpheus

As medical research pushes back the veil on the causes of certain well-known diseases, we are sometimes surprised at the unlikely culprits. It sounds obvious today, for instance, that cigarette smoking can cause lung cancer: one can easily picture the smoke snaking down to the lungs and leaving a nasty deposit. Sometimes, however, the connection … Continue reading

Jargon: Central Dogma of Molecular Biology (That DNA makes RNA which makes proteins)

The central dogma of molecular biology: The idea that, within a cell, information is transcribed from DNA into RNA and is translated from RNA to proteins. The DNA molecule is essentially a book containing the blueprints to make everything; RNA is a short copy of the blueprint that is necessary at a given moment; and … Continue reading
