What is Phage? 噬菌体 (bacteriophage,简称phage),是一种以细菌(bacteria)和古细菌(archaea)为宿主的病毒。它分布广泛,且数量巨大(地球上含有超过1031个噬菌体)。1915年,英国人Frederick Twort观察到可能的噬菌体溶菌现象(未证实),并发表在柳叶刀。1915年噬菌体被法籍加拿...
What is an Aptamer? The term “Aptamer” was coined by Andy Ellington. It stems from the Latin terms “aptus,” meaning to fit, and “meros,” meaning part. Aptamers are short, single-stranded DNA or RNA (ssDNA or ssRNA) molecules that can selectively bind to a specific target, includin...
+ssRNA viruses The RNA of these viruses (e.g. Picornaviridae and Flaviviridae etc) acts as the mRNA. During replication, the RNA-dependent RNA polymerase (of the virus) replicates the genome. Here, the genome (+ssRNA) is transcribed to produce -ssRNA that in turn serves as a template to...
SARS-CoV-2 is a positive-polar single-stranded RNA (ssRNA) virus belonging to the genus Betacoronavirus group 2B. Genomic analyses have shown that it has 79.6% genomic sequence identity to SARS-CoV, which caused the outbreak of severe acute respiratory syndrome (SARS) in 2002, and 50% ...
DGCR8 an important cofactor is required for the processing of pri-miRNA and is believed to recognize the cleavage site between ssRNA and stem of pri-miRNA. MicroRNAs as haematopoiesis regulators HCV is a member of the Flaviviridae family that bears approximately 10 kb long positive sense single-st...
The key difference between snRNA and snoRNA is that snRNA involves the alternative splicing of pre-mRNA while snoRNA involves modifying rRNA and tRNA, mRNA

What is a type or phase of the virus life cycle during which the virus integrates into the host chromosome of the infected cell, often remaining essentially dormant for some period of time? Explain the difference between a lytic and a lysogenic pathway of viral infection. ...
Since a human-derived cell line, HEK293, is used, human hepatitis A, HAV (~27-32nm, ssRNA, non-enveloped virus) and herpes simplex virus 1, HSV-1, (~ 155-200nm, dsDNA, enveloped virus) could be tested. It is worth mentioning that regulatory authorities accept only data from viral ...
This sug- gests that the iridescence color is caused by diffraction, which was demonstrated by an experiment using an argon ion laser illuminat- ing the shell to produce a distinct diffraction image. The strength of the iridescence color can be correlated to both the groove density of the ...
