Ribosomal RNA

Ribosomal ribonucleic acid, or rRNA, is the principle component of the ribosome and is crucial in the development of proteins for living cells. Approximately 80-85% of a cell’s total RNA is made up of rRNA. The low molecular weight transfer RNA (tRNA), which aids in bringing amino acids to the site of ribosomal translation, comprises only 15-20%. The remaining 1-5% is made up by messenger RNA (mRNA), which is essentially the encoding blueprint for the synthesis of a given protein. Proteins are

ABSTRACT: An independently folding RNA G-quadruplex (GQ) forming domain interacts with the 40S ribosomal subunit and determines their binding affinity and function of an internal ribosomal entry site (IRES). The interaction begins to shed light to theprovide possible mechanistic role of RNA GQ structures in cap-independent translation initiation. RNA G-quadruplexes (GQ) structures are secondary nucleic acid structures are that can act as both necessary elements of translation and as translation

modern science, one of these is the study on the rRNA which lead to the conclusion that the nucleolus is the site of ribosomal RNA synthesis and nascent ribosome assembly.1 In the early 70s it was observed that the ribonu-cleoprotein precursors to ribosomes contain two classes of protein. The difference between these proteins was thought to be that one class could be recognized as ribosomal proteins,

Christianah Sobukonla 11/25/14 DNA sequence and Dependent culture in Microbial Diversity Biodiversity is also known as the biological diversity. Biodiversity refers to all kinds of organism that can be found in a particular area.it includes a variety of plants, animals, fungi and other living things. Biodiversity of an ecosystem, is a community of animals, plants, and living things

Bacteria are very important in the recycling of wastewater. These facultative bacteria have the capability to thrive in or out of the presence of oxygen. They also help breakdown organic materials that could be harmful to the environment. However too much bacteria in a wastewater plants could create a big problem for wildlife and the ecosystem. This research will test the proliferation of bacteria before and after heavy rain to see if the rainwater run-off from farms that use fertilizers, and fish

RNA GQ structures in cap-independent translation initiation. RNA G-quadruplex (GQ) is a secondary structure that can act as both necessary elements of translation and as translation repressors.1-3 The role of GQ structures in translational modulation depends on the context in which the GQ structure is present.4 However, it is well established that these structures mostly inhibit translation.2,5-7 In fact, rational introduction of GQ structures specifically downregulate the expression of targeted

What influences affected whether an adolescent would trade sex for drugs or money. Can this be predicted by assessing the involvement and connection with parent(s)? Are there different degrees of parental participation that will predict if youths will exchange sex for drugs or money? 3. Which were the dependent and independent variables? Dependent variable- children that disclosed exchanging sex for drugs or money. Independent variable- participation of the parents in the youth’s lives. 4

We report the community of thermophilic bacteria cultivated from Tanjung Sakti Hot Spring in South Sumatera Indonesia that has temperature 80 – 91 0C and pH 7 – 8. Based on phylogenetic analysis, the 16 sequences of 16S rRNA gene fragments obtained from the community clustered within four distinct genera as Anoxybacillus, Geobacillus, Brevibacillus, and Bacillus. Two sequences that have 96% similarity with data sequences in GenBank, are potentially as novel species/sub species. Hot spring is a unique

Molecular and phylogenetic characterization of mercury reductase gene (merA) from newly isolated Bacillus sp. Introduction: Continuous discharge of industrial waste results in the increase levels of metal ions, which are toxic in nature. Among plethora of metals, mercury is found to be more toxic metals, whose metal ions are readily released from industries and anthropogenic sources. Mercury is one of potent neurotoxin and is also toxic to environment. The uncontrolled discharge of mercury as pollutant

ABSTRACT The important biological macromolecule polyhydroxybutyrate (PHB) producing Bacillus subtilis was isolated from the sewage sample and identified by means of 16S rRNA analysis. The renewable nature and biodegradability of PHBs make them suitable materials to replace synthetic plastics in many applications. Currently their production is expensive, but these plastics are only in their first stage of commercial development. In the present study the physico-chemical parameters such as Time, Temperature
