Decades of research have resulted in a remarkably detailed understanding of the molecular mechanisms of bacterial DNA replication, transcription and translation. Our understanding of the kinetics and physical mechanisms that drive these processes forward has been expanded by the ability of single-molecule in vitro techniques, such as force spectroscopy and single-molecule Forster fluorescence resonance energy transfer smFRET , to capture short-lived intermediate states in complex pathways. Furthermore, these technologies have revealed novel mechanisms that support enzyme processivity and govern the assembly of large multicomponent complexes. Here, we summarize the application of in vitro single-molecule studies to the analysis of fundamental bacterial processes, with a focus on the most recent functional insights that have been gained from fluorescence-based methods. Bacterial replication, transcription and translation : mechanistic insights from single-molecule biochemical studies. N2 - Decades of research have resulted in a remarkably detailed understanding of the molecular mechanisms of bacterial DNA replication, transcription and translation.

Description

Transcription begins with a bundle of factors assembling at the promoter sequence on the DNA in red. Here, two transcription factors are already bound to the promoter. Other proteins arrive, carrying the enzyme RNA polymerase in blue. To initiate transcription, these assembled proteins require contact with activator proteins that bind to specific sequences of DNA known as enhancer regions. What you are about to see is DNA's most extraordinary secret—how a simple code is turned into flesh and blood. It begins with a bundle of factors assembling at the start of a gene.

In both prokaryotes and eukaryotes, the second function of DNA the first was replication is to provide the information needed to construct the proteins necessary so that the cell can perform all of its functions. The mRNA then provides the code to form a protein by a process called translation. Through the processes of transcription and translation, a protein is built with a specific sequence of amino acids that was originally encoded in the DNA. This module discusses the details of transcription. The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma [link] , which states that genes specify the sequences of mRNAs, which in turn specify the sequences of proteins.

If the gene encodes a protein , the transcription produces messenger RNA mRNA ; the mRNA, in turn, serves as a template for the protein's synthesis through translation. This is because the positive-sense strand contains the information needed to translate the viral proteins for viral replication afterwards. This process is catalyzed by a viral RNA replicase.

Мой Бог. Это была настоящая красотка. - Спутница? - бессмысленно повторил Беккер.  - Проститутка, что. Клушар поморщился: - Вот .

 Подождите… сейчас посмотрю… отлично… - Сорок пять секунд! - раздался крик. Сьюзан взглянула на ВР. Последний защитный слой был уже почти невидим. - Вот оно! - воскликнула Соши. - Читайте! - Джабба обливался.  - В чем разница.

 - Как бы там ни было, ты поможешь мне с моей рукописью. - Рукописью. - Да. Я решила ее издать. - Издать? - Он с сомнением покачал головой.  - Издать .
