Why are nucleotides important molecules for cells?
They are the primary source of energy for the cell.
They build the cell membrane and control what enters and exits the cell.
They allow cells to transmit hereditary information and carry the instructions to build proteins.
They are not important, they are only used when the cell runs out of energy.

Builds the replicated strand of DNA.
Carries the message from DNA outside the nucleus.
Transfers the amino acid to the polypeptide at the ribosome.
