Viruses aren't made out of cells.
Sedimentary rocks are formed by cementation and compaction. This happens when sediment particles are compressed and fused together over very long periods of time.
The answer is proteins.
The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life.
