Promoter proximal elements are regulatory DNA sequences located near the core promoter of a gene, typically within 100-200 base pairs upstream of the transcription start site. They play a crucial role in the regulation of gene expression by serving as binding sites for transcription factors and other regulatory proteins. These elements can enhance or repress transcription, depending on the specific factors that interact with them. Their proximity to the core promoter allows them to influence the recruitment of the transcriptional machinery effectively.
Enhancers are at considerable distances from the promoter and can be moved or inverted and still function. Promoter-proximal elements are close to the promoter and their position and orientation must be maintained.
In eukaryotes, the interaction of enhancer and promoter elements is brought closer by the bending of DNA. Proteins called transcription factors bind to enhancer elements and recruit complexes that help bend and loop the DNA, bringing the enhancer and promoter regions into close proximity for efficient gene expression.
Obligatory water reabsorption occurs in the proximal convoluted tubule of the nephron in the kidney. This process helps to maintain the body's water balance by reabsorbing a majority of the filtered water back into the bloodstream.
The olecranon is known as the proximal end of the forearm. The proximal end of the forearm refers to the olecranon.
The limbs (arms and legs) are proximal to the body's trunk.
Enhancers are at considerable distances from the promoter and can be moved or inverted and still function. Promoter-proximal elements are close to the promoter and their position and orientation must be maintained.
Yes, cDNA does not have a promoter region because it is synthesized from mRNA and lacks the regulatory elements found in genomic DNA.

Proximal means closer to the origin of the limb, so the knee is proximal to the ankle, and the wrist is proximal to the thumb.
Proximal
Proximal, anything closer to midsection in proximal (closer) than distal (distant).
The opposite of a promoter is a detractor, someone who undermines or speaks against something.
