Proteins, starch, and DNA are similar in that they are all
(1) organic compounds
(2) parts of genes
(3) made of amino acids
(4) made of simple sugars
Answer and Explanation:
Proteins, starch and DNA are all important molecules in our body. What do they have in common? Well let's take a look at the answer choices and figure out. Only starch is made of simple sugars, while proteins are made of amino acids, and DNA contain genes that code our genetic information. Therefore, choice 1 is correct. Indeed, proteins, starch and DNA are all considered to be organic compounds. Organic compounds are molecules that contain carbon in them, oftentimes containing hydrogen and oxygen. All of the compounds listed above contain carbon and are therefore organic.
