3. How does the cell use both DNA and RNA to direct protein synthesis?

proteins are made in the cell cytoplasm on tiny structures called ribosomes, to make proteins ribosomes use a code in the DNA

DNA is found in the cells nucleus and cannot move, so the cell needs to get the code from the DNA to the ribosome this is done using a molecule called RNA (mRAN) - which is made by copying the code from DNA, the RNA acts as a messenger between the DNA and the ribosome - it carries the code between the two
