Significance Human immunodeficiency virus 1 (HIV-1) infection causes a life-long disease, due to the ability of the virus to integrate into the host genome and establish latent infection.

Background Transposable elements (TEs) are fragments of DNA that can insert into new chromosomal locations. They represent a great proportion of eukaryotic genomes.

Endogenous retroviruses (ERVs) are genetic elements present in the genome that retain traces of past viral infections. Characterization of ERVs can provide crucial insights into avian evolution.

Functional characterization of enhancer activity during a long terminal repeat\u27s evolution [PDF]
Many transposable elements (TEs) contain transcription factor binding sites and are implicated as potential regulatory elements. However, TEs are rarely functionally tested for regulatory activity, which in turn limits our understanding of how TE ...

Background Transcription from the integrated HIV-1 promoter is directly governed by its chromatin environment, and the nucleosome-1 downstream from the transcription start site directly impedes transcription from the HIV-1 promoter. The HIV-1 Tat protein

Reverse Transcription in the Saccharomyces cerevisiae Long-Terminal Repeat Retrotransposon Ty3
Converting the single-stranded retroviral RNA into integration-competent double-stranded DNA is achieved through a multi-step process mediated by the virus-coded reverse transcriptase (RT).

Periodicity in recurrent fast radio bursts and the origin of ultra long period magnetars [PDF]
The recurrent fast radio burst FRB 180916 was recently shown to exhibit a 16 day period (with possible aliasing) in its bursting activity. Given magnetars as widely considered FRB sources, this period has been attributed to precession of the magnetar spin axis or the orbit of a binary companion. Here, we make the simpler connection to a {\it rotational

On the nature of embedded precursors in long outbursts of SS Cyg stars as inferred from observations of the IW And star ST Cha [PDF]
We observed the IW And-type dwarf nova ST Cha and found that standstills were terminated by brightening at a constant brightness level during standstills. This finding is not consistent with a model of IW And-type dwarf novae assuming repeated enhancements of the mass-transfer rate from the secondary. We found that one outburst in ST Cha had a shoulder

Long terminal repeat retrotransposons (LTR-RTs) make up a considerable portion of plant genomes. New insertions of these active LTR-RTs modify gene structures and functions and play an important role in genome evolution.

Interaction of the v-rel protein with an NF-kappa B DNA binding site [PDF]
The avian reticuloendotheliosis virus T contains within its genome the oncogene rel. The expression of this gene is responsible for the induction of lymphoid tumors in birds.
