Nuclear ribosomal RNA (rRNA) genes represent the oldest repetitive fraction universal to all
eukaryotic genomes. Their deeply anchored universality and omnipresence during …

Abstract The 5S ribosomal DNA (rDNA) consists of one transcriptional unit of about 120
base pairs, which is separated from the next unit by a non-transcribed spacer (NTS). The …

There is mounting evidence that the ribosome is not a static translation machinery, but a cell-
specific, adaptive system. Ribosomal variations have mostly been studied at the protein …

In higher eukaryotes, the 5S ribosomal multigene family (5S rDNA) is tandemly organized in
repeat units composed of a coding region (5S rRNA gene) and a nontranscribed spacer …

To enhance our understanding of the organization of the genome and chromosome
evolution of cichlid fish species, we have isolated and physically mapped onto the …

Primary studies on whole sequenced genomes focused on single genes and little attention
was directed to repetitive DNAs, and duplicated segments. Single-and few-copy sequences …

Plant parasitic nematodes belonging to the genus Pratylenchus, also known as root lesion
nematodes, cause serious economic damage to different crop plants. In order to explore …

Background Ribosomal 5S genes are well known for the critical role they play in ribosome
folding and functionality. These genes are thought to evolve in a concerted fashion, with …

The genotoxic effects of cadmium chloride (CdCl2) and azadirachtin (Aza) were assessed
singly and conjointly in a fish, Oreochromis mossambicus, with endpoints such as …

In the present study dual-colour fluorescence in situ hybridization (FISH) was performed to
study the chromosomal distribution of 18S and 5S rDNAs,(GATA) n and 5S rDNA, and U2 …
