Promoter-dependent in vitro transcription reveals oligo(T) length-dependent terminator readthrough by RNAP III C1 mutants.

open access: yes, 2016
A) Schematic of tRNA gene arrangement used for in vitro transcription by S100 extracts; the plasmids used for transcription differed only in the number of Ts at the test terminator, T1, as listed above the lanes of B & C.

Transcription Factors and Termination of Transcription in Methanococcus [PDF]

open access: yesSystematic and Applied Microbiology, 1993
Summary We have recently shown that specific transcription in cell extracts of Methanococcus thermolithotrophicus depends upon a transcription factor that was separated from the RNA polymerase by phosphocellulose chromatography. Here, we provide evidence for a second transcription factor.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

A Bacillus subtilis phage φ29 transcription terminator is efficiently recognized in Streptomyces lvidans

open access: yes, 1987
Short communicationA DNA fragment from the Bacillus subtilis phage φ29, containing the bidirectional transcription terminator TD1, where the right early transcription and late viral transcription terminate, has been inserted in one orientation between ...

The function of the protein phosphatase Glc7p in transcription termination, RNA processing and transcriptional regulation of ribosomal protein genes [PDF]

open access: yes, 2007
Gene transcription in general can be subdivided into three main phases: transcription initiation, elongation and termination. The enzyme that accomplishes transcription of protein coding genes, snRNAs and snoRNAs is RNA polymerase II (RNAP II).

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Entre ‘terminator’ y ‘frankencell [PDF]

open access: yes, 1999
Una sola palabra bien buscada puede ser más eficaz que cien argumentos cuando se trata de desacreditar cualquier idea o iniciativa, del mismo modo que las caricaturas guiñolescas están haciendo estragos entre nuestros personajes públicos.

Automatic transcription of polyphonic music exploiting temporal evolution [PDF]

open access: yes, 2012
PhDAutomatic music transcription is the process of converting an audio recording into a symbolic representation using musical notation. It has numerous applications in music information retrieval, computational musicology, and the creation of ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

A Novel Mechanism for Transcription Termination in the mod(mdg4) Locus of Drosophila melanogaster

open access: yesBiology
This study investigated an alternative mechanism of transcription termination that occurs independently of polyadenylation. We focused on a non-canonical transcription terminator (NTT) identified in the mod(mdg4) gene of Drosophila melanogaster.
