SARS-CoV-2 is an extremely contagious respiratory virus causing adult atypical pneumonia COVID-19 with severe acute respiratory syndrome (SARS). SARS-CoV-2 has a single-stranded, positive-sense RNA (+RNA) genome of ~ 29.9 kb and exhibits significant genetic shift from different isolates. Afte...
Full size image The extent of public availability of SARS-CoV-2 genomic data varied across countries and variants; less than half of the sequences of Alpha, Beta, Gamma and Delta variants were publicly available in 36.1% (22/61), 17.0% (8/47), 16.2% (6/37) and 33.3% (18/54) coun...

2020年3月13日,杜克-新加坡国立大学医学院在bioRxiv上上传了一篇题为Discovery of a 382-nt deletion during the early evolution of SARS-CoV-2的研究,研究在新加坡住院的8名确诊患者体内发现了一种SARS-CoV-2的突变毒株,几乎包含了整个ORF8区域的382bp缺失,该缺失还删除了ORF8的转录调控序列(TRS),这反过来增强...
Bidirectional genome-wide CRISPR screens reveal host factors regulating SARS-CoV-2, MERS-CoV and seasonal HCoVs Article25 July 2022 Introduction In early December 2019, a new transmissible infection spread widely in China1, which caused a respiratory illness termed severe acute respiratory syndrome cor...

Coronavirus sickness (COVID-19) is associate degree communicable disease caused by a completely unique severe acute metabolic process syndrome coronavirus two (SARS-CoV-2) that originally started in metropolis province in China and has currently affected >200 countries worldwide and declared a plague[...
The genome of RaTG13 is 96.2% similar to SARS-CoV-2. That of RmYN02 is 93.3 % similar. Given that the SARS-CoV-2 genome is made up of 30,000 nucleotides (aka letters), the genetic distance between RaTG13 and SARS-CoV-2 is a significant 1,200 nucleotides. Under normal ...
Caco-2 cells were treated with 2 μmol/L ISRIB and infected with SARS-CoV-2 GFP ΔN virus at an MOI of 0.05. Twenty-four hours post-infection, whole-cell RNAs were purified for RT-qPCR to analyze viral genome abundance. Viral genomic RNA expression was normalized to that of the DMSO-...
both groups have only one signature mutation each (G26144T for SS2 and G11083T for SS3), which may show little phylogenetically useful difference for differentiating strains from these groups, when considering the integral size of the SARS-CoV-2 genome and its biological tendency to maintain con...
