Genetic information is encoded in DNA molecules.
Item RH020003: DNA provides information for both the types and sequence of amino acids that make up a protein molecule.
Which of the following does DNA provide information for?
- Both the types of amino acids that make up a protein, and the sequence of those amino acids
- The types of amino acids that make up a protein molecule, but not the sequence of amino acids
- The sequence of amino acids that make up a protein molecule, but not the types of amino acids
- Neither the types of amino acids that make up a protein, nor the sequence of those amino acids

- Disciplinary Core Ideas
- LS1.C The sugar molecules thus formed contain carbon, hydrogen, and oxygen: their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.
LS3.A Genes are located in the chromosomes of cells, with each chromosome pair containing two variants of each of many distinct genes. Each distinct gene chiefly controls the production of specific proteins, which in turn affects the traits of the individual. Changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits. - Notes
- The fact that DNA controls the production of proteins is included in NGSS, but the mechanism is not specified.
