Promoter - Genome.

Sep 21, 2022 . A promoter, as related to genomics, is a region of DNA upstream of a gene where relevant proteins (such as RNA polymerase and transcription factors) bind to initiate transcription of that gene. The resulting transcription produces an RNA molecule (such as mRNA)..

CpG site - Wikipedia.

CpG islands in promoters. In humans, about 70% of promoters located near the transcription start site of a gene (proximal promoters) contain a CpG island.. Distal promoter elements also frequently contain CpG islands. An example is the DNA repair gene ERCC1, where the CpG island-containing element is located about 5,400 nucleotides upstream of the transcription start site of the ERCC1 ....

Transcription (biology) - Wikipedia.

Transcription regulation at about 60% of promoters is also controlled by methylation of cytosines within CpG dinucleotides (where 5' cytosine is followed by 3' guanine or CpG sites). 5-methylcytosine (5-mC) is a methylated form of the DNA base cytosine (see Figure). 5-mC is an epigenetic marker found predominantly within CpG sites. About 28 million CpG dinucleotides ....

Expression using the T7 RNA polymerase/promoter system.

Consequently, the addition of rifampicin to cells that are producing T7 RNA polymerase results in the exclusive expression of genes under the control of a T7 RNA polymerase promoter (p(T7)). In the Basic Protocol, two plasmids are maintained within the same E. coli cell. One (the expression vector) contains p(T7) upstream of the gene to be ....

transcription factor | Definition, Effects, & Types | Britannica.

transcription factor, molecule that controls the activity of a gene by determining whether the gene's DNA (deoxyribonucleic acid) is transcribed into RNA (ribonucleic acid). The enzyme RNA polymerase catalyzes the chemical reactions that synthesize RNA, using the gene's DNA as a template. Transcription factors control when, where, and how efficiently RNA polymerases ....

Transcription Factors - an overview | ScienceDirect Topics.

Transcription factors are proteins that bind to the upstream regulatory elements of genes in the promoter and enhancer regions of DNA and stimulate or inhibit gene expression and protein synthesis. 1,58 They play critical roles in embryogenesis and development. Transcription factors may be tissue specific or may be present in a variety of ....

RiceXPro.

The Rice Expression Profile Database (RiceXPro) is a repository of gene expression profiles derived from microarray analysis of tissues/organs encompassing the entire growth of the rice plant under natural field conditions, rice seedlings treated with various phytohormones, and specific cell types/tissues isolated by laser microdissection (LMD). This database is part of a project on rice ....

T-DNA FAQ - Salk Institute for Biological Studies.

A: The T-DNA may insert in more than one place within the Arabidopsis genome. Due to the nature of the T-DNA integration event and the limitations of the PCR border recovery protocol, PCR products are sequenced directly without separating the products of each reaction. Thus, some sequencing reactions may contain two or more overlapping sequences..
