The other task I gave them on day I was to name the 20 amino acids that are produced by the "Universal" genetic code: this was an obvious task because there were 19+1=20 of us in the room. The quality of this student cohort is indicated by one of them briskly pulling me up on the "20 amino acids" because she knew that in some species in some circumstances the UGA 'stop' codon is induced to produce the 21st amino acid selenocysteine. I opened a box of chocolates, threw down a couple of markers and said they could have a sweet IF they could write the three-letter code for any of the known protein amino-acids. The quality of this student cohort is indicated by one of them asking me about taurine which is (almost) an amino acid which led to a brief discussion about other amino acids (ornithine) that have key roles in biology but not in building proteins. It was very brief because there was an unseemly scrum of students round the white board fighting for access to markers and chocolates. The tide didn't go down until all the dupes had been removed and the last amino acid had been identified. The quality of this student cohort is indicated by the fact that they stuck at it until they had solved the problem to their own satisfaction - the chocolates were entirely incidental.

These people, from all over the world but currently in Dublin, are hot. If you senior guys in Kiev "Привіт колеги" are looking to hire bright, engaged, competent young scientists you'd better be putting a competitive package together: there are only 19 currently available. If you young guys "Привіт прохолодні молоді люди" in Kiev are looking for a great taught Master's Program, I look forward to meeting you next year.
