Question

Which of the groups of organic molecules below would be expected to contain Nitrogen?

a nucleic acids
b carbohydrates
c none of the above
d fatty acids
e steroids

Answer 1

Nucleic acids and proteins are the organic molecules that contain nitrogen, as nucleic acids include nitrogenous bases and proteins are made up of amino acids that contain nitrogen.

Step-by-step explanation:

The groups of organic molecules that would be expected to contain nitrogen are nucleic acids and proteins. These two are among the four major classes of organic compounds.

Nucleic acids, such as DNA and RNA, are made up of nucleotides, which contain a nitrogenous base, a sugar, and a phosphate group. The nitrogenous bases are organic molecules that specifically include nitrogen atoms. Nitrogen is also a component of amino acids, which are the building blocks of proteins. Therefore, it is essential in the structure of both nucleic acids and proteins.
