Studies on protein-encoding DNA and RNA viruses and nonprotein-encoding viroids make a significant contribution to the understanding of macromolecular cell-to-cell and long-distance movement in plants. Most plant viruses have an RNA genome (vRNA), which is usually single stranded. RNA viruses are...
In particular, viruses are the only organisms on this planet to still have RNA as their sole genetic material. They are also the only autonomously replicating organisms to have single-stranded DNA genomes. Single-stranded RNA virus genomes may be positive-sense (i.e., the same polarity or ...
What is RNA? You have probably heard of DNA (Deoxyribonucleic Acid). All human cells have DNA. DNA is a sequence of four different kinds of molecules (A,T,C,G), which can be arranged in millions of different combinations of varying lengths to code for all of the genes of your body....
Viruses are small particles of genetic material (either DNA or RNA) that are surrounded by a protein coat. Some viruses also have a fatty "envelope" covering. They are incapable of reproducing on their own. Viruses depend on the organisms they infect (hosts) for their very survival. Viruses...
Current CRISPR-Cas based diagnostic technologies employ mainly Cas12 and Cas13 enzymes that possess either viral DNA or RNA-stimulated collateral DNase or RNase activities, respectively20. The Cas13-based methods21,22,23 detect the viral RNA by RNA-stimulated cleavage of RNA probes. The Cas12-...
溶瘤痘苗病毒(VV)属于痘病毒科中一拥有192kb双螺旋DNA遗传物质的病毒,会在细胞质中繁殖出具有鞘膜的病毒,进而感染其他不同种的哺乳动物细胞及个体.VV中的A27L基因能表达出一14kDa大小的鞘膜蛋白,此蛋白能与细胞表面上的硫酸乙酰肝素(Heparan Sulfate)作用使病毒跟细胞结合并且可催化细胞融合。

or even HIV/AIDS in the early 1980s. New techniques, however, now enable scientists to identify viruses by directly studying RNA or DNA sequences in genetic material associated with humans, enabling detection of whole populations of viruses—termed the virome—including those that may not cause ...
