Explain how RNA functions as an intermediary in protein synthesis.

• RNA directly forms proteins without any other molecules

• RNA serves as a template for DNA replication

• RNA translates the genetic code from DNA to synthesize proteins

• RNA stores genetic information permanently

Describe the process by which ATP serves as a carrier of chemical energy in cells.

• ATP is broken down into ADP and phosphate, releasing energy

• ATP is converted into DNA to store energy

• ATP is used to build cell walls

• ATP is stored in the nucleus for future use
