1. Transcription is the process by which mRNA is synthesized from a DNA template resulting in the transfer of genetic information from the DNA molecule to mRNA. DNA makes RNA
2. Translation is the process by which mRNA, tRNA, and ribosomes effect the production of a protein molecule from amino acids, the specificity of synthesis being controlled by the base sequences of the mRNA.
RNA makes protein
3. Replication is the production of exact copies of complex molecules, such as DNA molecules, that occurs during growth of living organisms.
DNA makes more of itself (DNA)
