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

C. Organic molecule, since dna is an organic compound

Answer 2

Answer:

The correct option is C.

Explanation:

DNA means deoxyribonucleic acid. DNA is a complex organic molecule because two of his constituents (the nitrogenous bases and the 5-carbon sugars) are organic compounds. Since these organic compounds form the basis of a DNA structure, then DNA can be said to be organic. These constituents are said to be organic because of the presence of carbon, hydrogen and the functional groups present in there structure.
