Anti-Termination It is possible for prokaryotic RNA polymerase to ignore termination signals and continue to transcribe until a downstream termination signal is reached. This mechanism is used by lambda phage. The lambda N gene codes for pN which interacts with polymerase RNA to enable it to read through to genes further downstream. Another antiterminator called […]

Prokaryotes are able to regulate gene expression by applying unique tricks in their toolbox. In prokaryotic cells, genes expression is regulated almost entirely at the level of the initiation of transcription. In eukaryotic cells, regulation of gene expression can occur at all stages of transcription and translation, and even after a protein is made. I […]
