Question

DNA molecules store genetic information and allow for self-replicating life. Molecules of DNA can be long and very complex. They always consist of smaller molecules that are made up of nitrogenous bases, phosphate groups, and 5-carbon sugars.
DNA is an example of a complex _______.

 A. 

carbohydrate polymer

 B. 

inorganic molecule

 C. 

organic molecule

 D. 

protein structure

​

Answer 1

The correct answer is C. Organic molecule.

Explanation

An organic molecule is a chemical compound that can contain carbon, oxygen, nitrogen, sulfur, among other elements. One of the chemical compounds that can be produced by the union of chemical elements are nucleotides, consisting of five carbons, a nitrogenous base, and a phosphate group. Likewise, when several nucleotides are linked they form longer and more complex chains such as nucleic acids, such as DNA or RNA, where genetic information of living organisms is stored. According to the above, DNA is a complex example of organic molecules. So, the correct answer is B. Organic molecule.

Answer 2

The answer would be C., Organic Molecule.
