Answer
The genetic code is made up of nitrogenous bases.
Solution
The components of DNA that are referred to as the genetic code are the nitrogenous bases.
Here’s a brief explanation of the options:
- F Phosphate groups: These are part of the backbone of the DNA structure but do not carry genetic information.
- G Nitrogenous bases: These are the components that encode genetic information. The four bases (adenine, thymine, cytosine, and guanine) pair up to form the genetic code.
- H Deoxyribose sugars: These are also part of the DNA backbone and do not carry genetic information.
- 3 Hydrogen bonds: These are interactions between the nitrogenous bases that help stabilize the DNA structure but are not components of the genetic code itself.
Thus, the correct answer is G Nitrogenous bases.

The genetic code is primarily written in the sequence of nitrogenous bases found in DNA. These bases—adenine (A), thymine (T), cytosine ©, and guanine (G)—pair up in specific ways (A with T and C with G) to form the building blocks of our genetic information. Each combination of these bases determines different traits, like a widow’s peak or attached earlobes.
In the DNA structure, deoxyribose sugar serves as the backbone that supports the nitrogenous bases. Together with phosphate groups, it forms the double helix structure. However, it’s the sequence of those nitrogenous bases that encodes the genetic instructions our cells use to build proteins and carry out their functions!
