Transcription is the process by which an RNA polymerase synthesizes ribonucleic acid (RNA) using deoxyribonucleic acid (DNA) as a template. Aryl hydrocarbon receptor (AHR) is an emerging immune ...

This manuscript describes an important finding of the transcriptional control of a chimeric gene transfer agents (GTA) cluster in Bartonella by a processive anti-termination factor (BrrG). The ...

Through the activation and repression of the target genes, transcription factors (TFs) determine the fate of cells within tissues, organs and organisms, controlling the development. Most TFs act ...

In this study, the viral RNAs from five clinical samples and cultured SARS-CoV-2 variants were quantified with a reverse transcription digital droplet PCR (RT-ddPCR) and sequenced as whole-genomes ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing ...

MicroRNAs (miRNAs) are small, non-coding, RNA molecules approximately 22 nucleotides in length which act as post-transcriptional regulators of gene expression. Individual miRNAs have been shown to ...

Most DNA molecules consist of two polymers (double-stranded) of four nucleotides that each consist of a nucleobase, the carbohydrate deoxyribose and a phosphate group, where the carbohydrate and ...
