Reconstructing phylogeny from RNA secondary structure via simulated evolution

open access: yes, 2002
DNA sequences of genes encoding functional RNA molecules (e.g., ribosomal RNAs) are commonly used in phylogenetics (i.e. to infer evolutionary history).

The isolation of differentially expressed cDNA clones from the filarial nematode Brugia pahangi [PDF]

open access: yes, 1999
A cDNA library constructed from 3 day post-infective L3 of the filarial nematode Brugia pahangi was screened by differential hybridization with cDNA probes prepared from different life-cycle stages.

Multiple prebiotic metals mediate translation. [PDF]

open access: yes, 2018
Today, Mg2+ is an essential cofactor with diverse structural and functional roles in life's oldest macromolecular machine, the translation system. We tested whether ancient Earth conditions (low O2, high Fe2+, and high Mn2+) can revert the ribosome to a ...

Antibiotic resistance evolved via inactivation of a ribosomal RNA methylating enzyme. [PDF]

open access: yes, 2016
Modifications of the bacterial ribosome regulate the function of the ribosome and modulate its susceptibility to antibiotics. By modifying a highly conserved adenosine A2503 in 23S rRNA, methylating enzyme Cfr confers resistance to a range of ribosome ...

Distinct RNA profiles in subpopulations of extracellular vesicles: apoptotic bodies, microvesicles and exosomes [PDF]

open access: yes, 2013
Introduction: In recent years, there has been an exponential increase in the number of studies aiming to understand the biology of exosomes, as well as other extracellular vesicles.

Function of Plant DExD/H-Box RNA Helicases Associated with Ribosomal RNA Biogenesis

open access: yesFrontiers in Plant Science, 2018
Ribosome biogenesis is a highly complex process that requires several cofactors, including DExD/H-box RNA helicases (RHs). RHs are a family of ATPases that rearrange the secondary structures of RNA and thus remodel ribonucleoprotein complexes. DExD/H-box

HCV IRES manipulates the ribosome to promote the switch from translation initiation to elongation. [PDF]

open access: yes, 2013
The internal ribosome entry site (IRES) of the hepatitis C virus (HCV) drives noncanonical initiation of protein synthesis necessary for viral replication.

In vitro Assessment of RNA Polymerase I Activity

open access: yesBio-Protocol, 2017
In eukaryotic cells transcriptional processes are carried out by three different RNA polymerases: RNA polymerase I which specifically transcribes ribosomal RNA (rRNA), RNA polymerase II which transcribes protein-coding genes to yield messenger RNAs ...
