Here's a general overview of DNA's role:
* DNA is the blueprint of life: It contains the genetic instructions for building and maintaining an organism.
* Stores and transmits genetic information: DNA holds the code for all the proteins and RNA molecules that make up a cell and carry out its functions.
* Passed down from generation to generation: Through replication, DNA copies itself so each new cell receives a complete set of instructions.
With the specific statements, I can tell you which one most accurately reflects this essential function.
