Question: Mexico City has numerous museums dedicated to art, including Mexican colonial, modern and contemporary art, and international art. The Museo Tamayo was opened in the mid-1980s to house the collection of international contemporary art donated by famed Mexican (born in the state of Oaxaca) painter Rufino Tamayo. The collection includes pieces by Picasso, Klee, Kandinsky, Warhol and many others, though most of the collection is stored while visiting exhibits are shown. The Museo de Arte Moderno (Museum of Modern Art) is a repository of Mexican artists from the 20th century, including Rivera, Orozco, Siqueiros, Kahlo, Gerzso, Carrington, Tamayo, among others, and also regularly hosts temporary exhibits of international modern art.

Question: The proportion of non-repetitive DNA is calculated by using the length of non-repetitive DNA divided by genome size. Protein-coding genes and RNA-coding genes are generally non-repetitive DNA. A bigger genome does not mean more genes, and the proportion of non-repetitive DNA decreases along with increasing genome size in higher eukaryotes.
Is there an answer to this question: What is the size of non-repetitive DNA divided by to get the proportion of non-repetitive DNA?

Answer: genome size

Question: In 1966 an agreement with the Vatican, fostered in part by the death in 1960 of anti-communist archbishop of Zagreb Aloysius Stepinac and shifts in the church's approach to resisting communism originating in the Second Vatican Council, accorded new freedom to the Yugoslav Roman Catholic Church, particularly to catechize and open seminaries. The agreement also eased tensions, which had prevented the naming of new bishops in Yugoslavia since 1945. Tito's new socialism met opposition from traditional communists culminating in conspiracy headed by Aleksandar Rankovic. In the same year Tito declared that Communists must henceforth chart Yugoslavia's course by the force of their arguments (implying an abandonment of Leninist orthodoxy and development of liberal Communism). The State Security Administration (UDBA) saw its power scaled back and its staff reduced to 5000.
Is there an answer to this question: What acronym describes the State Security Administration?

Answer:
UDBA
