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:
Primary group would include the following:
-a close-knit group of adult friends who have been together since middle school
-a married couple
Secondary group would include the following:
-a tailoring shop that makes bespoke (fully custom) suits for men
-a professional football team
Explanation:
When the members of a social group share very close and lasting relationships, such group is considered a primary group. Members in this group shows concern for each other and most time carried each other's burdens. For example, family, influential social groups, and childhood friendship.
On the other hand, secondary groups consist of people who interactions are strictly outcome-based or business-related or interaction between members are done on a less personal level.
Answer:
Ang pagtingin sa isang pelikula nang kritiko at maingat na nangangahulugang upang mapagtanto ang sinehan na may higit na pag-iisip at kamalayan, at upang maiangat ang isang karanasan sa celluloid. Nangangahulugan din ito ng pagkakaroon ng isang kaalamang kaalaman tungkol sa kumplikado at siksik na 'wika ng pelikula,' ang mga kombensyon, code, simbolo, cinematic na katangian, at iba pang mga kadahilanan.
Answer:
Quantitative
Explanation:
In quantitative research an observable phenomenon is studied and analyzed via mathematical, statistical, or computational techniques. It is generally done in order to prove or validate a hypothesis. Numerical data is used in this type of research.
In qualitative research non numerical data is recorded by observing phenomena.
Here, the respondents are asked to answer a question according to the scale provided. This data will then be statistically analyzed and conclusions will be drawn hence this type of research is quantitative research.
