The virus is part of a larger group of related bacteria, including phages (viruses that infect and replicate within specific types of bacteria) such as QP, F2, and GA. Bacteria such as Mycobacterium tuberculosis, Bacillus anthracis, and Clostridium botulinum are known to be infected by certain phages, which are known as Bacteriophages. Not limited to genomic sequences unlike hybridization-based approaches, which may require species-specific probes, RNA-seq can detect transcripts from organisms with previously undetermined genomic sequences. It serves the purpose of protein-synthesizing, elongation, initiation, and termination of polypeptide synthesis, For various functional and structural studies, For increasing the yield of RNA at the time of RNA isolation or extraction. Bacteriophage MS2 ( Emesvirus zinderi ), commonly called MS2, is an icosahedral, positive-sense single-stranded RNA virus that infects the bacterium Escherichia coli and other members of the Enterobacteriaceae. Medical Science 2. First, the PCR is converted from single-stranded RNA to double-stranded DNA in a process called reverse transcription. In addition, the lack of time-intensive cell passages and propagations means that MS2 studies are performed at reduced cost relative to other viruses. The mass spectrum of a compound not only provides information about the mass of the parent compound (from the m/z value of its ion), but also helps to elucidate the structure of the compound from the relative abundances of isotopic mass peaks.
