What type of molecule is DNA?

Lipid
Carbohydrate
Nucleic acid
Protein

The correct answer is: Nucleic acid

DNA is a type of molecule known as a nucleic acid. It is composed of long chains of nucleotides that contain genetic information essential for all living organisms. Lipids, such as fats and oils, are important for energy storage and cell membrane structure but they do not contain genetic information like DNA does. Carbohydrates, such as sugars and starches, provide energy but they are not involved in storing genetic information. Although proteins are essential for various functions in the body, they are not the same as DNA. DNA is unique as it is the only molecule that contains the instructions for building and maintaining an organism.
