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

Answer:
A. the Industrial Revolution.
Explanation:
When one begins to study the Industrial Revolution, the first question to raise is what kind of revolution we are talking about. Often we understand the word "revolution" as a revolt, a dispute between political groups, or even a civil war in a given society. But that is not the point here.
The meaning we use in this case is that of revolution as a profound transformation, a very big change, a break from what was before. When we speak, then, of an "industrial revolution", we are talking about a drastic change in the way man-made products are manufactured, this change has been so strong that we can say that the changes in technology that underlie sustained growth that we observed today began at that time.
The answer is B) The Jews had mixed feelings about the romans.
Jews in general didnt want to interact with other cultures but they didnt like the romans because of the rule but they did see some positive things about the role of the Romans
