Coronavirus subgenomic minus-strand RNAs (negative-strand copies of the 3' coterminal subgenomic mRNAs) probably function in mRNA amplification by serving as templates for transcription from internal (intergenic) promoters, rather than by faithful (full-length) mRNA replication.
冠状病毒亚基因组负链RNA(3' 共末端亚基因组mRNA的负链拷贝)可能通过作为内部(基因间)启动子转录的模板来发挥mRNA扩增功能,而不是通过忠实的(全长)mRNA复制。
