Antibiotic resistant characteristics from 16S rRNA [PDF]
arXiv, 2012 Background: Microbiota have evolved to acclimate themselves to many environments. Humanity is become ever increasingly medicated and many of those medications are antibiotics. Sadly, Microbiota are adapting to medication and with each passing generation they become more difficult to subdue.

The complete mitochondrial genome of Anas penelope (Anatidae: Anas)
Mitochondrial DNA. Part B. Resources, 2020 The complete mitochondrial DNA genome of the Eurasian Wigeon, Anas penelope, was mapped by the next-generation sequencing and Mega 7.0. The circular mitogenome (16,596 bp in length) contains 13 protein-coding genes, 2 rRNA genes (12S ribosomal RNA and ...

Molecular Genetics & Genomic Medicine, 2019 Background Ribosomal RNA (rRNA) consists of four non‐coding RNAs, the 28S, 5.8S, 18S, and 5S rRNA. Abnormal expression of rRNA has been found in multiple tumors, and the methylation of rDNA promoter may affect rRNA expression as an epigenetic regulatory ...

The unknotted strands of life: knots are very rare in RNA structures [PDF]
arXiv, 2014 The ongoing effort to detect and characterize physical entanglement in biopolymers has so far established that knots are present in many globular proteins and also abound in viral DNA packaged inside bacteriophages. RNA molecules, on the other hand, have not yet been systematically screened for the occurrence of physical knots.

Isolation and organization of calf ribosomal DNA
Nucleic Acids Research, 1979 Ribosomal DNA (rDNA) from calf was isolated by three density gradient centrifugations. The first centrifugation in Cs2S04/BAMD was used to obtain partially resolved dG+dC-rich fractions from total DNA. The second and third centrifugations, in Cs2S04/Ag+, led to the isolation of an rDNA fraction characterized by a symmetrical band in CsCl, p = 1.724 g ...

Nuclear eDNA metabarcoding primers for anthozoan coral biodiversity assessment [PDF]
PeerJThe distributions of anthozoan corals are undercharacterized due to their wide bathymetric ranges, occurrences in remote locales, and difficulties of identification from morphology alone.

Molecular interactions between the constituents of small ribosomal subunit [PDF]
arXiv, 2012 Availability of high-resolution crystal structures of ribosomal subunits of different species opens a route to investigate about molecular interactions between its constituents and stabilization strategy. Structural analysis of the small ribosomal subunit shows that primary binder proteins are mainly employed in stabilizing the folded ribosomal RNA by ...

RIBOSOMAL DNA IN A NUCLEAR SATELLITE OF TOMATO [PDF]
Genetics, 1975 ABSTRACT A satellite DNA of buoyant density 1.704 constitutes approximately 5%–6% of nuclear DNA isolated from cherry tomato leaves. Isolated satellite DNA exhibits a multi-component melting profile. Kinetic complexity measurements indicate that 37% of the satellite consists of repeating units of 105 daltons, and 48% of it consists of ...

Slowing translation to avoid ribosome population extinction and maintain stable allocation at slow growth rates [PDF]
arXivTo double the cellular population of ribosomes, a fraction of the active ribosomes is allocated to synthesize ribosomal proteins. Subsequently, these ribosomal proteins enter the ribosome self-assembly process, synthesizing new ribosomes and forming the well-known ribosome autocatalytic subcycle.
