Tombusvirus internal replication element (IRE)
Encyclopedia
In virology
, the tombusvirus internal replication element (IRE) is a segment of RNA
located within the region coding for p92 polymerase. This element is essential for viral replication
; specifically, it is thought to be required at an early stage of replication, such as template recruitment and/or replicase complex assembly.
Other non-coding RNA
structures in Tombusvirus include the 3' UTR region IV
and 5' UTR
.
Virology
Virology is the study of viruses and virus-like agents: their structure, classification and evolution, their ways to infect and exploit cells for virus reproduction, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy...

Viral replication
Viral replication is the term used by virologists to describe the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. From the perspective of the virus, the purpose of viral replication is...

Non-coding RNA
A non-coding RNA is a functional RNA molecule that is not translated into a protein. Less-frequently used synonyms are non-protein-coding RNA , non-messenger RNA and functional RNA . The term small RNA is often used for short bacterial ncRNAs...
