Abstract Nucleic acids are the blueprint of life. They are not only the construction plan of the single cell or higher associations of them, but also necessary for function, communication and regulation. Due to the pandemic, the attention shifted in particular to their therapeutic potential as a vaccine. As pharmaceutical oligonucleotides are unique in

Kinetic Proofreading and the Limits of Thermodynamic Uncertainty [PDF]
To mitigate errors induced by the cell's heterogeneous noisy environment, its main information channels and production networks utilize the kinetic proofreading (KPR) mechanism. Here, we examine two extensively-studied KPR circuits, DNA replication by the T7 DNA polymerase and translation by the E. coli ribosome. Using experimental data, we analyze the

Species delimitation in the African Armillaria complex by analysis of the ribosomal DNA spacers.
Thirteen Armillaria isolates, collected from various geographical areas in tropical Africa and previously characterized by cultural morphology, pairing tests and isozyme analysis, were evaluated using the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP).

Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

Coarse-Grained model of the demixing of DNA and non-binding globular macromolecules [PDF]
The volume occupied by the unconstrained genomic DNA of prokaryotes in saline solutions is thousand times larger than the cell. Moreover, it is not separated from the rest of the cell by a membrane. Nevertheless, it occupies only a small fraction of the cell called the nucleoid.

Fixation Times of Retroposons in the Ribosomal DNA Spacer of Human and Other Primates
We have investigated the presence/absence of two types of retroposed sequences found in human ribosomal DNA in equivalent positions in chimpanzee, gorilla, orangutan, gibbon, and rhesus monkey rDNA. These sequences are one pseudogene derived from the single-copy cdc27hs gene and seven complete Alu elements.

Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force established the TASK3 working groups to create common data elements (CDEs) for various preclinical epilepsy research disciplines. The aim of the CDEs is to improve the standardization of experimental designs across a range of epilepsy ...

Genetic diversity of ‘Candidatus Phytoplasma mali’ strains in Poland
During 2010-2013, samples from 267 apple trees growing in six regions of Poland were tested for phytoplasma presence. ‘Candidatus Phytoplasma mali’ was detected in 17 samples from phloem tissue of apple shoots showing typical apple proliferation symptoms.

In human cells, ribosomal DNA (rDNA) is arranged in ten clusters of multiple tandem repeats. Each repeat is usually described as consisting of two parts: the 13 kb long ribosomal part, containing three genes coding for 18S, 5.8S and 28S RNAs of the ...
