√100以上 double-stranded rna viruses use for genome replication cellular enzymes true false 269511

The replication mechanism depends on the viral genome DNA viruses usually use host cell proteins and enzymes to make additional DNA that is transcribed to messenger RNA (mRNA), which is then used to direct protein synthesis RNA viruses usually use the RNA core as a template for synthesis of viral genomic RNA and mRNA

Double-stranded rna viruses use for genome replication cellular enzymes true false- Doublestranded RNA viruses carry their own RNA synthesizing enzymes within their virions Once inside a cell, the enzymes transcribe one of the RNA strands of the dsRNA genome to ssRNA() within the virion, which upon release into the cytoplasm (through channels in the virion) is translated by the host cell machineryE) Many RNA viruses contain either doublestranded RNA genomes or produce ds RNA molecules during replication One cellular enzyme that may be involved in antiviral defense is adenosine deaminase Adenosine deaminase modifies adenine bases in dsRNA converting them into inosine which has the pairing properties of guanine
