The DNA is definitely the code but I think proteins are code,data and the processor itself depending upon what role its playing in the cell. At molecular level protein structures can affect creation or destruction of other protein structures, they also act as logic-gates. So proteins are clearly part of the cell hardware that regulates the cell. They also act as messages and if-else control logic (its also called GNR, Gene Regulatory Network) to read different DNA chunks based on certain conditions, so in that way they are part of the code. So I think DNA is the code on the disk-drive but proteins is "in memory" code,data and the hardware itself.
