<u>The correct answer is A. He divided the empire into provinces and appointed a leader for each province</u>. From 539 BC to 331 BC, the <u>Persian Empire</u> was the most powerful state in the world and <u>Darius I</u>, who was King from 522 BC to 486 BC, divided that <u>Empire</u> into twenty large provinces, called <em><u>satrapies</u></em>. Each<em><u> satrapy</u></em> was governed by a<em><u> satrap or governor</u></em>. Their main responsibilities were to enforce law and order, and to collect taxes and tributes. To check the satraps, a secretary and a military official representing <u>Darius</u> were installed in every province. This division secured that he would not have to travel from one end of his empire to the other, defending the borders against every little tribe that decided to attack.
The first description of the DNA (deoxyribonucleic acid)chain was done by Watson and Crick in 1953, the nucleotides that constitute the DNA are four: cytosine (C), guanine (G), timine (T) and adenine (A). When doing a model is essential to remember that cytosine ONLY joins guanine and timine only link adenine, this is due to the size and chemical properties of each molecule. Later, another related and similar and molecule was discovered, the ribonucleic acid or RNA, which also is constructed by nucleotides.
In both cases, the nucleotides are compound of 3 main components: a nitrogen base, a pentose and a phosphate. When the molecule lacks the phosphate group, is called nucleoside. Depending on the chain ( DNA or RNA) the nitrogen base derives from purine (adenine and guanine) or pyrimidine (cytosine or timine) just in the RNA instead of timine is uracil (U)
The union is established between adjacent molecules through the phosphate, while among each other through the nitrogen base-remember C=G and T or U=A. The core of each molecule is the pentose. Therefore the best representation of the molecule is attached
