Problem: The vast majority of living organisms encode their genes in long strands of DNA (deoxyribonucleic acid). DNA consists of a chain made from four types of nucleotide subunits, each composed of: a five-carbon sugar (2'-deoxyribose), a phosphate group, and one of the four bases adenine, cytosine, guanine, and thymine.:2.1
What are the four bases used in nucleotide subunits?
The answer is the following: adenine, cytosine, guanine, and thymine

Problem: The Hanoverian king George II of Great Britain was passionately devoted to his family’s continental holdings, but his commitments in Germany were counterbalanced by the demands of the British colonies overseas. If war against France for colonial expansion was to be resumed, then Hanover had to be secured against Franco-Prussian attack. France was very much interested in colonial expansion and was willing to exploit the vulnerability of Hanover in war against Great Britain, but it had no desire to divert forces to central Europe for Prussia's interest.
Name two diverse geographies that king George II had to protect.
The answer is the following: his commitments in Germany were counterbalanced by the demands of the British colonies overseas

Problem: The WVS (Women's Voluntary Services for Civil Defence) was set up under the direction of Samuel Hoare, Home Secretary in 1938 specifically in the event of air raids. Hoare considered it the female branch of the ARP. They organised the evacuation of children, established centres for those displaced by bombing, and operated canteens, salvage and recycling schemes. By the end of 1941, the WVS had one million members. Prior to the outbreak of war, civilians were issued with 50 million respirators (gas masks). These were issued in the event of bombing taking place with gas before evacuation.
What group did Samuel Hoare set up in 1938?
The answer is the following: Women's Voluntary Services for Civil Defence

Problem: Firstly, flanking the open reading frame, all genes contain a regulatory sequence that is required for their expression. In order to be expressed, genes require a promoter sequence. The promoter is recognized and bound by transcription factors and RNA polymerase to initiate transcription.:7.1 A gene can have more than one promoter, resulting in messenger RNAs (mRNA) that differ in how far they extend in the 5' end. Promoter regions have a consensus sequence, however highly transcribed genes have "strong" promoter sequences that bind the transcription machinery well, whereas others have "weak" promoters that bind poorly and initiate transcription less frequently.:7.2 Eukaryotic promoter regions are much more complex and difficult to identify than prokaryotic promoters.:7.3
How is a promoter sequence recognized?
The answer is the following:
by transcription factors and RNA polymerase
