A parsimonay analysis of eukaryotic small subunit ribosomal RNA (″18 S″) sequences [PDF]

open access: yesArchives Internationales de Physiologie, de Biochimie et de Biophysique, 1993
Using the principles of Felsenstein's DNA parsimony analysis program (package PHYLIP 3.2), a program with the capacity to handle data sets of the magnitude of ss rRNA has been developed. With this program we applied an heuristic approach to 83 s rRNA sequences from the Antwerp data bank, compared along 4230 positions of their alignment.

Use of Internal Controls to Increase Quantitative Capabilities of the Ribonuclease Protection Assay

open access: yesBioTechniques, 1997
Through the use of two internal controls, we have developed an improved method of quantitating ribonuclease protection assay (RPA) results. A truncated sense RNA fragment and an antisense RNA fragment for the gene of interest were transcribed from PCR ...

The terminal sequences of Bombyx mori 18S ribosomal RNA

open access: yesNucleic Acids Research, 1975
The 5' and 3' terminal T1 oligonucleotides of 32p-labelled B. mori 18S ribosomal RNA were isolated by a two dimensional electrophoretic (diagonal) technique. Nucleotide sequence analysis showed that the 3' terminal fragment, (G)AUCAUUAOH, is identical to that previously obtained from the 18S rRNA of several other eukaryotic species. The sequence of the

Quantitative analysis of snoRNA association with pre-ribosomes and release of snR30 by Rok1 helicase [PDF]

open access: yes, 2008
In yeast, three small nucleolar RNAs (snoRNAs) are essential for the processing of pre-ribosomal RNA—U3, U14 and snR30—whereas 72 non-essential snoRNAs direct site-specific modification of pre-rRNA. We applied a quantitative screen for alterations in the

Evaluation of qPCR reference genes for taimen (Hucho taimen) under heat stress

open access: yesScientific Reports, 2022
As a powerful and attractive method for detecting gene expression, qRT-PCR has been broadly used in aquaculture research. Understanding the biology of taimen (Hucho taimen) has drawn increasing interest because of its ecological and economic value ...

The nucleolar RNA methyltransferase Misu (NSun2) is required for mitotic spindle stability [PDF]

open access: yes, 2009
Myc-induced SUN domain–containing protein (Misu or NSun2) is a nucleolar RNA methyltransferase important for c-Myc–induced proliferation in skin, but the mechanisms by which Misu contributes to cell cycle progression are unknown.

Rcl1 Protein, a Novel Nuclease for 18 S Ribosomal RNA Production [PDF]

open access: yesJournal of Biological Chemistry, 2011
In all forms of life, rRNAs for the small and large ribosomal subunit are co-transcribed as a single transcript. Although this ensures the equimolar production of rRNAs, it requires the endonucleolytic separation of pre-rRNAs to initiate rRNA production.

Temperature and Development Impacts on Housekeeping Gene Expression in Cowpea Aphid, Aphis craccivora (Hemiptera: Aphidiae).

open access: yesPLoS ONE, 2015
Quantitative real-time PCR (qRT-PCR) is a powerful technique to quantify gene expression. To standardize gene expression studies and obtain more accurate qRT-PCR analysis, normalization relative to consistently expressed housekeeping genes (HKGs) is ...

Molecular Identification of Trypanosoma evansi Isolated from Arabian Camels (Camelus dromedarius) in Riyadh and Al-Qassim, Saudi Arabia

open access: yesAnimals, 2021
We analyzed the blood from 400 one-humped camels, Camelus dromedarius (C. dromedarius), in Riyadh and Al-Qassim, Saudi Arabia to determine if they were infected with the parasite Trypanosoma spp.
