Which of the following are examples of nucleic acids? Select all that apply. a fatty acid a nucleotide a DNA molecule an amino acid an RNA molecule

## Step 1<br />Nucleic acids are a type of macromolecule that store and transmit genetic information. They are composed of monomers called nucleotides. <br /><br />## Step 2<br />The two main types of nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Both DNA and RNA are made up of nucleotides, which are the building blocks of nucleic acids.<br /><br />## Step 3<br />A fatty acid is a component of lipids, not nucleic acids. It is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated.<br /><br />## Step 4<br />An amino acid is a component of proteins, not nucleic acids. It is a molecule that contains both an amino group (-NH2) and a carboxylic acid group (-COOH).
