Q: Leke III Dukagjini (1410--1481), mostly known as Leke Dukagjini, was a mysterious member of the Dukagjini family about whom little is known and who is thought to have been a 15th-century Albanian nobleman.

A: What was the noble family that Lekë Dukagjini was from?

Q: Nowadays they are giving homework even during the holidays and I hate that very much. But I think there is a reason for it. Homework is given so that we can remember whatever we have learnt. Regular drilling and repetition make perfect. But teachers have started to give too much homework. Anything in excess is bad. Jane What's the use of just homework without allowing children to get an insight into the subject? It just makes them bookworms but nothing else. Homework such as writing some things 5 times at home will just make them memorize things but not put them into use. I regret to say that teachers find it easy to bundle the children with homework rather than making them get interested to understand what they learn. The same trend continues even in college. I find that most of the so-called high scorers are unable to answer simple things in an interview. Sally It is OK to give homework. But it should be given less. We are spending most of our time in school and at least we must be free in our home. If you give homework, we will be very tired and we wouldn't be able to pay attention to extra-curricular activities, which in turn may affect our physical and mental health. So please give less homework to us. Johnson It is part of our work to give students homework. There will be some punishments if we won't do our work. So I have to do that though I know such a teacher is not liked by students.

A: Who thinks homework should help students learn something practical?

Q: Selenoproteins are an elite group of proteins containing a rare amino acid, selenocysteine (Sec), encoded by the codon, UGA. In eukaryotes, incorporation of Sec requires a Sec insertion sequence (SECIS) element, a stem-loop structure located in the 3'-untranslated regions of selenoprotein mRNAs. Here we report identification of a noncanonical form of SECIS element in Toxoplasma gondii and Neospora canine, single-celled apicomplexan parasites of humans and domestic animals. This SECIS has a GGGA sequence in the SBP2-binding site in place of AUGA previously considered invariant. Using a combination of computational and molecular techniques, we show that Toxoplasma and Neospora possess both canonical and noncanonical SECIS elements. The GGGA-type SECIS element supported Sec insertion in mammalian HEK 293 and NIH 3T3 cells and did so more efficiently than the natural mammalian SECIS elements tested. In addition, mammalian type I and type II SECIS elements mutated into the GGGA forms were functional but manifested decreased Sec insertion efficiency. We carried out computational searches for both AUGA and GGGA forms of SECIS elements in Toxoplasma and detected five selenoprotein genes, including one coding for a previously undescribed selenoprotein, designated SelQ, and two containing the GGGA form of the SECIS element. In contrast, the GGGA-type SECIS elements were not detected in mammals and nematodes. As a practical outcome of the study, we developed pSelExpress1, a vector for convenient expression of selenoproteins in mammalian cells. It contains an SBP2 gene and the most efficient tested SECIS element: an AUGA mutant of the GGGA-type Toxoplasma SelT structure.

A:
What is the name of the stem loop present in the 3' end of genes encoding for selenoproteins?
