Abstract:
Ribosomal RNA gene dosage was determined for 20 marine heterotrophic bacteria using short probes (< 600 bp) from the Escherichia coli 16S rRNA gene and Southern blot analysis. All Bacterial strains had between 4 and 10 copies of the 16S rRNA genes in their genomes. This report presents important preliminary data for developing quantitative molecular methods to address population dynamics of marine based of 16S rRNA sequences.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Bacterial RNA Polymerase
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...
Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
