Exempel på hur man kan använda OPERONS i en mening

• Originally, operons were thought to exist solely in prokaryotes (which includes organelles like plastids that are derived from bacteria), but their discovery in eukaryotes was shown in the early 1990s, and are considered to be rare.
• These elements are bound by specific uncharged tRNAs and modulate the expression of corresponding aminoacyl-tRNA synthetase operons.
• This terminology is generally, although not exclusively, used in reference to prokaryotes, whose genomes are often organized into operons; the genes contained within a regulon are usually organized into more than one operon at disparate locations on the chromosome.
• Processive antitermination was first discovered in a bacteriophage, but examples have since been found in bacterial operons.
• Beisel and Storz demonstrated with microarray analysis and reporter fusions that Spot 42 plays a broader role in metabolism by regulating at least 14 operons.
• But then genes coding for proteins homologous to those of the carboxysome shell were identified in the pdu (propanediol utilization) and eut (ethanolamine utilization) operons.
• Many lacto-2 RNAs are present in operons that encode tRNAs and rRNAs, and many are adjacent to genes encoding protein subunits of the ribosome, although they are not necessarily in the same operon as these protein-coding genes.
• It works by the fact that Hpr is phosphorylated by a specific mechanism, when glucose enters through the cell membrane protein EIIC, and when Hpr is phosphorylated it can then allow CcpA to block transcription of the alternative sugar pathway operons at their respective cre sequence binding sites.
• Lacto-usp RNAs are found exclusively in lactic acid bacteria, and exclusively in the possible 5′ untranslated regions of (5′ UTRs) operons that contain a hypothetical gene and a usp gene.
• It is found in most species within the family Pseudomonadaceae, and is consistently located in the 5' untranslated regions (5' UTRs) of operons that contain groES genes.
• However, transcripts provide insufficient information for gene prediction because they might be unobtainable from some genes, they may encode operons of more than one gene, and their start and stop codons cannot be determined due to frameshifts and translation initiation factors.
• Transcriptional antiterminators of the BglG/SacY family are regulatory proteins that mediate the induction of sugar metabolizing operons in Gram-positive and Gram-negative bacteria.
• The Nif regulon is a set of seven operons used to regulate nitrogen fixation in the coliform bacterium Klebsiella pneumoniae under anaerobic and microaerophilic conditions.
• Moreover, RNA-Seq is an important approach for identifying coregulated genes, enabling the organization of pathogen genomes into operons.
• Bioinformatic analyses have revealed that some ACR3 porters are involved in operons together with ArsA-like ATPases, implying that some of these porters may be driven by ATP hydrolysis as primary active transporters.
• Other characteristic features of cryptophyte mtDNAs include large syntenic clusters resembling α-proteobacterial operons that encode bacteria-like rRNAs, tRNAs, and ribosomal protein genes.
• DUF3268 RNAs are consistently found in the 3′ untranslated regions (UTRs) of operons that include genes which encode the conserved protein domain DUF3268, sigma factors and signal peptidases.
