研究人员近日利用一种量化单分子测序技术,探测到人类细胞中一类新型小分子RNA(核糖核酸),在基因转录方面代表着一个全新的种类,并证实了长久以来的一种假设,哺乳动物细胞能通过直接复制RNA分子来合成RNA。这一研究由美国匹兹堡大学医学院、瑞士日内瓦大学医学院和两家生物科技公司共同进行。这是首次证明人类细胞能像复制DNA一样复制RNA。匹兹堡大学医学院计算与系统生物学教授、
Researchers recently used a quantitative single-molecule sequencing technique to detect a new class of small RNAs (RNAs) in human cells that represent a whole new category in gene transcription and confirm a long-held assumption that lactation Animal cells can synthesize RNA by directly replicating RNA molecules. The study was conducted by the University of Pittsburgh Medical School, the University of Geneva Medical School and two biotech companies. This is the first demonstration of human cells replicating RNA like DNA. Professor of Computing and Systems Biology, University of Pittsburgh Medical School,
