DNA transposons generally move by "cut and paste" in the genome, but duplication has also been observed. Class 2 TEs do not use RNA as intermediate and are popular in bacteria, in metazoan it has also been found.

In September 1975, Gaddafi purged the army, arresting around 200 senior officers, and in October he founded the clandestine Office for the Security of the Revolution. In 1976, student demonstrations broke out in Tripoli and Benghazi, and were attacked by police and Gaddafist students. The RCC responded with mass arrests, and introduced compulsory national service for young people. Dissent also arose from conservative clerics and the Muslim Brotherhood, who were persecuted as anti-revolutionary. In January 1977, two dissenting students and a number of army officers were publicly hanged; Amnesty International condemned it as the first time in Gaddafist Libya that dissenters had been executed for purely political crimes.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many senior officers were expelled fro the army in 1975?
Ah, so.. 200

Utrecht city has an active cultural life, and in the Netherlands is second only to Amsterdam. There are several theatres and theatre companies. The 1941 main city theatre was built by Dudok. Besides theatres there is a large number of cinemas including three arthouse cinemas. Utrecht is host to the international Early Music Festival (Festival Oude Muziek, for music before 1800) and the Netherlands Film Festival. The city has an important classical music hall Vredenburg (1979 by Herman Hertzberger). Its acoustics are considered among the best of the 20th-century original music halls.[citation needed] The original Vredenburg music hall has been redeveloped as part of the larger station area redevelopment plan and in 2014 has gained additional halls that allowed its merger with the rock club Tivoli and the SJU jazzpodium. There are several other venues for music throughout the city. Young musicians are educated in the conservatory, a department of the Utrecht School of the Arts. There is a specialised museum of automatically playing musical instruments.
