Prevalent use and evolution of exonic regulatory sequences in the human genome

open access: yesNatural Sciences, 2023
It has long been known that exons can serve as cis‐regulatory sequences, such as enhancers. However, the prevalence of such dual‐use of exons and how they evolve remain elusive.

Geographical distribution of Brucella melitensis inferred from rpoB gene variation

open access: yesJournal of Infection in Developing Countries, 2017
Introduction: Currently available tests have limitations for the identification of Brucella species and strains, and their genetic lineage. The genome sequence of the rpoB gene encoding the β-subunit of DNA-dependent RNA polymerase was investigated for ...

The Mechanisms of Codon Reassignments in Mitochondrial Genetic Codes [PDF]

open access: yes, 2007
Many cases of non-standard genetic codes are known in mitochondrial genomes. We carry out analysis of phylogeny and codon usage of organisms for which the complete mitochondrial genome is available, and we determine the most likely mechanism for codon ...

Translation elongation can control translation initiation on eukaryotic mRNAs [PDF]

open access: yes, 2013
Synonymous codons encode the same amino acid, but differ in other biophysical properties. The evolutionary selection of codons whose properties are optimal for a cell generates the phenomenon of codon bias.

Candidate essential genes in Burkholderia cenocepacia J2315 identified by genome-wide TraDIS

open access: yesFrontiers in Microbiology, 2016
Burkholderia cenocepacia infection often leads to fatal cepacia syndrome in cystic fibrosis patients. However, antibiotic therapy rarely results in complete eradication of the pathogen due to its intrinsic resistance to many clinically available ...

Codon Bias Patterns of $E.coli$'s Interacting Proteins [PDF]

open access: yes, 2015
Synonymous codons, i.e., DNA nucleotide triplets coding for the same amino acid, are used differently across the variety of living organisms. The biological meaning of this phenomenon, known as codon usage bias, is still controversial.

Intracellular management of information: from DNA to proteins

open access: yestripleC: Communication, Capitalism & Critique, 2009
The living features of cells constitute an information flow from a central database, the nuclear DNA, to molecular effectors, proteins, which are synthesised in the cytoplasm.

Analysis of p53 codon 72 polymorphism and HPV 5,8 E6 oncoprotein expression in Basal cell carcinoma in Basrah [PDF]

open access: yesThe Medical Journal of Basrah University, 2016
Background: Two polymorphic forms of the p53 gene that codes either for Arginine or proline at codon 72 were identified, However, this individual might have one of the three genotypes: Arginine/Arginine, Proline/Proline or Arginine /Proline.

Translation initiation factor eIF3 promotes programmed stop codon readthrough. [PDF]

open access: yes, 2015
Programmed stop codon readthrough is a post-transcription regulatory mechanism specifically increasing proteome diversity by creating a pool of C-terminally extended proteins.

Expanding codon size

open access: yeseLife, 2022
Engineering transfer RNAs to read codons consisting of four bases requires changes in tRNA that go beyond the anticodon sequence.
