Transcription preinitiation complex, represented by the central cluster of proteins, causes RNA polymerase to bind to target DNA site. The PIC is able to bind both the promoter sequence near the gene to be transcribed and an enhancer sequence in a different part of the genome, allowing enhancer sequences to regulate a gene distant from it.
RNA polymerase I. RNA polymerase 1 (also known as Pol I) is, in higher eukaryotes, the polymerase that only transcribes ribosomal RNA (but not 5S rRNA, which is synthesized by RNA polymerase III ), a type of RNA that accounts for over 50% of the total RNA synthesized in a cell. [1]
DNA polymerase I (or Pol I) is an enzyme that participates in the process of prokaryotic DNA replication. Discovered by Arthur Kornberg in 1956, [1] it was the first known DNA polymerase (and the first known of any kind of polymerase ). It was initially characterized in E. coli and is ubiquitous in prokaryotes.
A DNA polymerase is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replication and usually work in groups to create two identical DNA duplexes from a single original DNA duplex. During this process, DNA polymerase ...
Its name is often abbreviated to Taq or Taq pol. It is frequently used in the polymerase chain reaction (PCR), a method for greatly amplifying the quantity of short segments of DNA . T. aquaticus is a bacterium that lives in hot springs and hydrothermal vents , and Taq polymerase was identified [1] as an enzyme able to withstand the protein ...

PLGA, PLG, or poly (lactic-co-glycolic acid) ( CAS: 26780-50-7 ) is a copolymer which is used in a host of Food and Drug Administration (FDA) approved therapeutic devices, owing to its biodegradability and biocompatibility. [1] PLGA is synthesized by means of ring-opening co-polymerization of two different monomers, the cyclic dimers (1,4 ...
