Coronavirus 5′ UTR
From Wikipedia, the free encyclopedia
Coronavirus genomes are positive-sense single-stranded RNA molecules with an untranslated region (UTR) at the 5′ end which is called the 5′ UTR. The 5′ UTR is responsible for important biological functions, such as viral replication, transcription[1] and packaging.[2] The 5′ UTR has a conserved RNA secondary structure but different Coronavirus genera (Alpha-, Beta-, Gamma-, and Deltacoronaviruses) have different structural features described below.
