Your Name in Protein

Thanks to the internet, you can find out your pirate name and your Jersey Shore name, and now thanks to the EMBL-EBI learning tools, you can find your protein name too! When you type your name into the box, the program reads the letters of your name as if they were the single-letter codes for…

Extracting Genetic Material

The first (and sometimes 3rd, 12th, 25th, 134th…) step of any genetic engineering experiment is often extracting DNA from some organism or another. While novel gene synthesis technology will likely make this procedure obsolete, these days it’s still most economical to do it by hand. Extracting DNA from fruits like strawberries has also seen a…

A recent New York Times article tells us that what many people call food allergies are actually simple intolerances, and that allergies are being dangerously overdiagnosed. What is a true food allergy, and what can be done to fix them besides banning peanuts from schools and avoiding foods that make us itchy? Allergies are caused…

Expanding the Genetic Code

Almost every living thing shares an identical genetic code, with three nucleic acids in an RNA sequence coding for a single amino acid in the translated protein sequence. While there are 64 three-letter RNA sequences, there are only 20 amino acids and degeneracy in the code allows some amino acids to be coded by multiple…
