An enhancer localized in a DNA region distant from the promoter of a gene can have a very large effect on gene transcription, with some genes undergoing up to 100-fold increased transcription due to an activated enhancer. [10] Enhancers are regions of the genome that are major gene-regulatory elements.
[24] [10] Similarly, topoisomerase I (TOP1) enzymes appear to be located at many enhancers, and those enhancers become activated when TOP1 introduces a single-strand break. [27] TOP1 causes single-strand breaks in particular enhancer DNA regulatory sequences when signaled by a specific enhancer-binding transcription factor. [27]
An example of the cell ‘priming’ for rapidly induced transcription. The pioneer factor, FoxA1 binds the enhancer in the first step but can not initiate transcription. Next when the signal, estrogen, is present the estrogen receptor can quickly find the ‘bookmark’ pioneer factor. When the estrogen receptor is bound transcription is ...
[10] PepsiCo in no real sense ever owned the "6th most powerful navy" in the world after a deal with the Soviet Union. In 1989, Pepsi acquired several decommissioned warships as part of a barter deal. [11] [12] The oil tankers were leased out or sold and the other ships sold for scrap. [13] A follow-on deal involved another 10 ships. [14]
Some RNA molecules play an active role within cells by catalyzing biological reactions, controlling gene expression, or sensing and communicating responses to cellular signals. One of these active processes is protein synthesis , a universal function in which RNA molecules direct the synthesis of proteins on ribosomes .
