Primordial helium recombination. I. Feedback, line transfer, and continuum opacity [PDF]

, 2007
Precision measurements of the cosmic microwave background temperature anisotropy on scales ℓ>500 will be available in the near future. Successful interpretation of these data is dependent on a detailed understanding of the damping tail and cosmological ...

Histone H3 Lysine 56 Acetylation Is Required for Formation of Normal Levels of Meiotic DNA Breaks in S. cerevisiae

Frontiers in Cell and Developmental Biology, 2020
Meiotic recombination is initiated by Spo11-catalyzed DNA double-strand breaks (DSBs) that are promoted by histone modifications and histone modifying enzymes. Herein we investigated the role of histone H3 lysine 56 acetylation (H3K56ac) located near the

Recombination in RNA

Cell, 1982
The aphthovirus genome consists of a single molecule of single-stranded RNA that encodes all the virus-induced proteins. We isolated recombinant aphthoviruses from cells simultaneously infected with temperature-sensitive mutants of two different subtype strains.

SUMOylation of Rad52-Rad59 synergistically change the outcome of mitotic recombination [PDF]

, 2016
Homologous recombination (HR) is essential for maintenance of genome stability through double-strand break (DSB) repair, but at the same time HR can lead to loss of heterozygosity and uncontrolled recombination can be genotoxic.

Recombination in Wolbachia [PDF]

Current Biology, 2001
Wolbachia are widely distributed intracellular bacteria that cause a number of reproductive alterations in their eukaryotic hosts. Such alterations include the induction of parthenogenesis, feminization, cytoplasmic incompatibility, and male killing [1-11].

Analysis of Recombinant Characteristics Based on 949 PRRSV-2 Genomic Sequences Obtained from 1991 to 2021 Shows That Viral Multiplication Ability Contributes to Dominant Recombination

Microbiology Spectrum, 2022
Porcine reproductive and respiratory syndrome (PRRS) is one of the most economically important diseases affecting the pig-raising industry. The PRRS virus (PRRSV) has high genetic diversity, partly owing to viral recombination.

RDP3: a flexible and fast computer program for analyzing recombination

Bioinform., 2010
Summary: RDP3 is a new version of the RDP program for characterizing recombination events in DNA-sequence alignments. Among other novelties, this version includes four new recombination analysis methods (3SEQ, VISRD, PHYLRO and LDHAT), new tests for ...

A Bismuth-Halide Double Perovskite with Long Carrier Recombination Lifetime for Photovoltaic Applications.

Journal of the American Chemical Society, 2016
Despite the remarkable rise in efficiencies of solar cells containing the lead-halide perovskite absorbers RPbX3 (R = organic cation; X = Br(-) or I(-)), the toxicity of lead remains a concern for the large-scale implementation of this technology.

The coronavirus proofreading exoribonuclease mediates extensive viral recombination

bioRxiv, 2020
Coronaviruses (CoVs) emerge as zoonoses and cause severe disease in humans, demonstrated by the SARS-CoV-2 (COVID-19) pandemic. RNA recombination is required during normal CoV replication for subgenomic mRNA (sgmRNA) synthesis and generates defective ...

Structural snapshots of Xer recombination reveal activation by synaptic complex remodeling and DNA bending [PDF]

, 2016
Bacterial Xer site-specific recombinases play an essential genome maintenance role by unlinking chromosome multimers, but their mechanism of action has remained structurally uncharacterized. Here, we present two high-resolution structures of Helicobacter
