Several students have been practicing drawing their models of nucleotides. Whose model do you think is most consistent with the
RSB [31]

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

What type of person if republics of oriented profession​
Wittaler [7]

Answer:

A profession is an occupation founded upon specialized educational training, the purpose of which is to supply disinterested objective counsel and service to others, for a direct and definite compensation, wholly apart from expectation of other business gain.[1][2] The term is a truncation of the term "liberal profession", which is, in turn, an Anglicization of the French term "profession libérale". Originally borrowed by English users in the 19th century, it has been re-borrowed by international users from the late 20th, though the (upper-middle) class overtones of the term do not seem to survive retranslation: "liberal professions" are, according to the European Union's Directive on Recognition of Professional Qualifications (2005/36/EC), "those practiced on the basis of relevant professional qualifications in a personal, responsible and professionally independent capacity by those providing intellectual and conceptual services in the interest of the client and the public".
