The central dogma of molecular biology is that DNA makes RNA, and RNA makes proteins. This process is called gene expression, and the genetic information is used within a cell to produce the proteins needed for the cell to function. More specifically, the information for making proteins resides...
The article reports on two studies related to the regulation of bacterial gene expression in response to different environmental conditions. It offers information on the co-relation of ribosomes and RNA polymerase where researchers used magnetic resonance spectroscopy, and streptomycin for binding and ...

Long interspersed nuclear element-1 (LINE-1 or L1) is a retrotransposon group that constitutes 17% of the human genome and shows variable expression across cell types. However, the control of L1 expression and its function in gene regulation are incompletely understood. Here we show that L1 tr...

Organisms determine the transcription rates of thousands of genes through a few modes of regulation that recur across the genome1. In bacteria, the relationship between the regulatory architecture of a gene and its expression is well understood for indiv
THE POINT: there are many ways for gene expression to be different from“normal”. Some of them cause problems and others do not or simply causeindividuals to vary slightly from the average. [3] Transcription Initiation What determines whether or not a gene is transcribed?
typically respond to signals from within the cell that indicate whether transcription is required. In many human genes, several transcription factors may be needed before transcription can proceed efficiently. A transcription factor can cause either repression or activation of gene expression in eukaryotes...
Gene expression from foreign promoters. Many proteins are expressed at low levels in vivo. To produce high levels of a protein, it is often useful to clone the gene downstream of a well-characterized, regulated promoter. Inducing transcription from the regulated promoter thus results in elevated ...
