Verified step by step guidance1
Identify the role of DNA in the cell by recalling its fundamental biological function.
Understand that DNA contains sequences called genes, which encode instructions for synthesizing RNA and proteins.
Recognize that these proteins and RNAs are essential for carrying out cellular functions and passing genetic information to offspring.
Eliminate options that describe functions not associated with DNA, such as structural roles in membranes, enzymatic catalysis, or energy provision.
Conclude that the primary function of DNA is to store and transmit hereditary information by encoding the instructions for building RNAs and proteins.
