Jargon: Exome (All of the DNA that makes it into mature RNA)

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

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

Jargon: Gene (A stretch of DNA that can be transcribed into a functional RNA molecule)

Gene: a stretch of DNA that can be transcribed into a functional RNA molecule. This RNA molecule is frequently, though not always, translated into a protein. Genes are always referred to as “functional units of inheritance”, which is not a fantastically intuitive concept. This one was given to us by a German who used the … Continue reading
