The nucleotide sequences of 5S rRNAs from three ciliated protozoa.
The nucleotide sequences of 5S rRNAs from three ciliated protozoa, Paramecium tetraurelia, Tetrahymena thermophila and Blepharisma japonicum have been determined. All of them are 120 nucleotides long and the sequence of probable tRNA binding site of position 41-44 is GAAC which is characteristic of the plant 5S rRNAs. The sequence similarity percents are 87% (Paramecium/Tetrahymena), 86% (Param...
متن کاملPrinciples of Intracellular Signaling in Ciliated Protozoa : A Brief Outline
Ciliates have available most of the intracellular signaling mechanisms known from metazoans. Long-range signals are represented by firmly installed microtubules serving as gliding rails aiming at specific targets. Many components are distinctly arranged to guarantee locally restricted effects. Short-range signals include Ca, provided from different sources, and proteins for membrane recognition...
متن کاملOmasal ciliated protozoa in cattle, bison, and sheep.
Omasal contents were collected from slaughtered cattle (n = 54), bison (n = 15), and sheep (n = 40) to determine numbers and generic distribution of ciliated protozoa. Total protozoan numbers were significantly lower in omasal contents than in ruminal contents of all three species, but the percent composition of all protozoan genera was similar between omasal and ruminal populations. The highes...
متن کاملAn Improved Silver Carbonate Impregnation for Marine Ciliated Protozoa
An improved silver carbonate impregnation method for marine ciliates is described. Compared to conventional methods, the new method of fixing and staining is easy to learn and yields easily reproducible results. Structures that are impregnated with silver carbonate such as nuclear apparatus, infraciliature as well as cortical and cytoplasmic microtubules and even contractile vacuole pore are st...
متن کاملStudies on the Metabolism of the Protozoa
A characteristic feature of euglenoid flagellates is that they synthesize granules of paramylon (paramylum) as reserve carbohydrate. We now report the results of a structural study of this polysaccharide from Astasia ocellata; a preliminary account of this work has been published (Manners, Ryley & Stark, 1964). Ast8ia ocellata is a freshwater flagellate (Class Euglenineae), being a nonphotosynt...
