Hybridization of plant ribosomal RNA to DNA: the isolation of a DNA component rich in ribosomal RNA cistrons.
Several studies of artificial hybridization between ribosomalRNA and homologous and heterologous DNA's from animal and bacterial sources have been reported. These studies indicate that there is a multiplicity of cistrons coding for ribosomal RNA,1-8 that these cistrons are located at the nucleolar organizer region of higher organisms,2' and that nucleotide sequences of ribosomal RNA tend to be ...
متن کاملthe 18s ribosomal dna sequence of strongyloides stercoralis in iran
background : strongyloides stercoralis is a prevalent parasite in some rural areas in the north of iran. we decided to investigate whether the 18s ribosomal dna sequence of the parasite in iran is similar to the findings of the other researchers. methods : we collected 3514 stool samples from gilan and mazandaran, northern iran, during the year 2005-2006, from which 96 were found infected wit...
متن کاملCleavage of adenovirus messenger RNA and of 28S and 18S ribosomal RNA by RNase III.
Escherichia coli ribonuclease III cleaves adenovirus messenger RNA and mammalian 28S and 18S ribosomal RNA. Fragmentation is not random, but in each case a specific collection of products is generated. This points to the potential use of the enzyme as a tool for specific fragmentation of RNA. Cleavage by RNase III abolishes the capability of adenovirus messenger RNA to direct cell-free synthesi...
متن کاملa contrastive analysis of concord and head parameter in english and azerbaijani
این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
15 صفحه اولCorrection: PCR Primers for Metazoan Nuclear 18S and 28S Ribosomal DNA Sequences
BACKGROUND Metagenetic analyses, which amplify and sequence target marker DNA regions from environmental samples, are increasingly employed to assess the biodiversity of communities of small organisms. Using this approach, our understanding of microbial diversity has expanded greatly. In contrast, only a few studies using this approach to characterize metazoan diversity have been reported, desp...
