Information-carrying macromolecule polymerization step.
| Elongation is the primary polymerization processes of DNA replication, transcription, and translation. |
An elongation step is seen in DNA replication, transcription, and translation. It follows various forms of initiation and involves the addition of subunits to DNA, RNA, or growing polypeptides by DNA polymerase, RNA polymerase, or ribosomes, respectively. This follows RNA priming, RNA polymerase binding, or ribosome binding and assembly, again respectively, for replication, transcription, and translation.
See also transcription initiation and translation initiation as well as transcription termination and translation termination. See also termination (molecular genetics). Further details associated with elongation steps can be found under DNA replication, transcription, and translation.
Elongation requires inputs of energy as the various polymerization steps involve dehydration synthesis reactions (i.e., condensation reactions).
