Biology CLEP Prep Practice Exam

DNA carries genetic information in the form of codes. These codes consist of a sequence of four nitrogenous bases - adenine, guanine, cytosine, and thymine - that make up the genetic code. These base pairs are arranged in specific sequences, and this sequence is what carries the genetic information needed for the development and functioning of living organisms. The other options - structures, lipids, and carbohydrates - are all incorrect as they do not play a role in carrying genetic information in cells. Structures in cells refer to the organization of different molecules and organelles, lipids are a type of molecule that make up the cell membrane, and carbohydrates are important for energy storage and cell structure. However, none of these play a role in the storage and transmission of genetic information.
