- NRC Framework
- LS1.A Genes contain the instructions that code for the formation of molecules called proteins, which carry out most of the work of cells to perform the essential functions of life. That is, proteins provide structural components, serve as signaling devices, regulate cell activities, and determine the performance of cells through their enzymatic actions.
- LS3.A In effect, proteins build an organism’s identifiable traits.
