Question

_______ are found in BOTH viruses AND in living single-celled organisms, such as protozoans and bacteria.

Answer 1

You could say DNA and RNA but I would use DNA to be more specific

Answer 2

DNA and RNA

Step-by-step explanation:

Nucleic acids (DNA and RNA) are found in both viruses and in living single-celled organisms, such as protozoa and bacteria. They are responsible for heredity and are the basis for building proteins that are essential to the body.

Both are made up of subunits - the nucleotides. Each nucleotide is formed by a 5-carbon sugar (deoxyribose, in DNA and ribose in RNA), a radical of phosphoric acid (phosphate) and a cyclic compound with nitrogen (the nitrogenous base). There are five types of nitrogenous bases: adenine (A), guanine (G), cytosine (C), thymine (T) and uracil (U). These molecules are responsible for the formation of genes.
