Here is a question about this article: Due to the chemical composition of the pentose residues of the bases, DNA strands have directionality. One end of a DNA polymer contains an exposed hydroxyl group on the deoxyribose; this is known as the 3' end of the molecule. The other end contains an exposed phosphate group; this is the 5' end. The two strands of a double-helix run in opposite directions. Nucleic acid synthesis, including DNA replication and transcription occurs in the 5'3' direction, because new nucleotides are added via a dehydration reaction that uses the exposed 3' hydroxyl as a nucleophile.:27.2
What is the answer to this question: What causes the directionality of DNA strands?
****
So... the chemical composition of the pentose residues of the bases

Here is a question about this article: Schwarzenegger was born in Thal, a village bordering the city of Graz in Styria, Austria and christened Arnold Alois. His parents were Gustav Schwarzenegger (August 17, 1907 December 13, 1972), and Aurelia Schwarzenegger (nee Jadrny; July 29, 1922 August 2, 1998).

According to Schwarzenegger, both of his parents were very strict: "Back then in Austria it was a very different world, if we did something bad or we disobeyed our parents, the rod was not spared." He grew up in a Roman Catholic family who attended Mass every Sunday.
What is the answer to this question: What was Schwarzenegger's dad's job in their town?

So... chief of police

Here is a question about this article: By the mid-18th century, Charles Town had become a bustling trade center, the hub of the Atlantic trade for the southern colonies. Charles Towne was also the wealthiest and largest city south of Philadelphia, in part because of the lucrative slave trade. By 1770, it was the fourth-largest port in the colonies, after Boston, New York, and Philadelphia, with a population of 11,000slightly more than half of them slaves. By 1708, the majority of the colony's population was slaves, and the future state would continue to be a majority of African descent until after the Great Migration of the early 20th century.
What is the answer to this question: Who made up the majority of Charles Town population in 1708?
****
So...
slaves
