Answer:

C. Nucleotides

Explanation:

Nucleic acids are macromolecules which are polymers of nucleotides. There are two types of nucleic acids namely: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleotides are the building blocks of nucleic acids.

A nucleotide is made up of three components:

- A phosphate group

- A five carbon sugar called pentose sugar. In RNA the sugar is ribose sugar and in DNA the sugar is deoxyribose sugar.

- Nitrogenous bases: There are four different types of bases in DNA: adenine, guanine, cytosine and thymine. In RNA thymine is replaced by uracil. Adenine and guanine are purines whereas cytosine, thymine and uracil are pyrimidines.

Nitrogenous base and sugar together are called nucleoside and when phosphate is also attached then it is called nucleotide.

How dose science influence the decisions made about social, economic, and political issues?
inysia [295]
This is a rather subjective question and has a lot to do with the type of society in which one lives. the more secular the world is becoming... gives science a huge spotlight on the stage. because science provides an answer with tons of evidence to back it up, it is seen as a reliable method to follow. So, socially speaking you may have experienced in a normal conversation where someone turns around and tells you that your opinions are just opinions and have nothing factual to back them up. This is where science comes in. Economically and politically speaking, science is used to justify different political aims of governments. However, this is done mostly through the misrepresentation of science by people who are trying to pursue their own agenda. So really this question can be answered in many ways and from many different perspectives but do not forget that science influences all streams for the better but also for the worse in the way in which it is represented.
