A Comparative Electron Microscopical Study of Rna from Different Sources
نویسندگان
چکیده
Electron micrographs of ribosomal RNA from Escherichia coli, microsomal RNA from calf, rat, and chick liver, Bacillus cereus RNA and E. coli soluble RNA are presented. Filaments of about 10 A in diameter could be observed in preparations obtained from aqueous solutions of high molecular weight RNA. When ammonium acetate solutions were used a tendency for coiling and aggregation was observed. E. coli soluble RNA appears as small, sometimes elongated particles the smallest diameter being of about 10 A.

Evaluation of β-actin as a Reference Gene for Comparative Expression Analysis of Equine Adipose- and Bone Marrow-Derived Mesenchymal Stem Cells by qRT-PCR
Background Bone marrow and adipose tissue are two main sources of mesenchymal stem cells (MSCs). Some of studies suggest that there are some differences in gene expression profile of MSCs-derived from various tissues. To investigate gene expression profile by qRT-PCR, an appropriate reference gene with stable expression level should be chosen for normalizing data. This study was designed to e...

Background: Stenotrophomonas maltophilia is an opportunistic bacterium, contributing to different hospital-acquired infections and can be acquired from different hospital setting sources. Epidemiological study of S. maltophilia in the hospital also demonstrates the intrahospital distribution of certain strains of bacteria in healthcare facilities. The aim of the current study was to identify th...
متن کاملElectron microscopical and biochemical characterization of infectious pancreatic necrosis virus.
An electron microscopical and biochemical examination of the properties of infectious pancreatic necrosis virus (IPN) and of its ribonucleic acid (RNA) was made. The buoyant density of IPN in CsCl was found to be 1.33 g/cm(3). Electron microscopical examination of the banded virus revealed structures similar in size (74 nm) and shape to reoviruses but lacking a characteristic inner capsid struc...

Nowadays, non-albicans Candida are common in human pathogens, and some of these cases were found in milk in the present study. Thanks to its various minerals and vitamins, milk is a good food source for humans and an ideal environment for the growth of microorganisms, including bacteria and fungi. Also, it is an important product in the agricultural sector. Materials and Methods: In the presen...
متن کاملThree-dimensional reconstruction of Trypanosoma brucei editosomes using single-particle electron microscopy.
RNA editing within the mitochondria of kinetoplastid protozoa is performed by a multicomponent -macromolecular machine known as the editosome. Editosomes are high molecular mass protein assemblies that consist of about 15-25 individual polypeptides. They bind pre-edited transcripts and convert them into translation-competent mRNAs through a biochemical reaction cycle of enzyme-catalyzed steps. ...
