| Protein Synthesis | takes place in the ribosomes, |
| codon | codes for a specific amino acid & consists of 3 nucleotides ex. ucc |
| Messenger RNA | mRNA |
| Transfer RNA | tRNA |
| Ribosomal RNA | rRNA |
| 3 Steps of Transcription | inititaion, elongation, termination |
| RNA synthesis | DNA to RNA |
| Initiation | The transcription enzyme RNA polymerase attaches to a specific region of the DNA. Region promotes transcription. |
| Elongation | RNA polymerase leaves the promoter region, and moves along the coding strand, elongating the RNA molecule |
| Termination | RNA polymerase reaches the terminater region or the end of the DNA. The newly synthesized RNA is released and RNA polymerase falls off. |
| RNA Processing | additiona and chemical modification of certain nucleotides and the removal of some segments from the RNA |
