With the polymerase now functioning in its elongation mode, a rudder-like structure in the enzyme continuously pries apart the DNA-RNA hybrid formed. The TATA box is typically located 25 nucleotides upstream from the transcription start site. Although eucaryotic RNA polymerase II has many structural similarities to bacterial RNA polymerase Figure , there are several important differences in the way in which the bacterial and eucaryotic enzymes function, two of which concern us immediately. The process of termination also is an example of a common theme in this chapter: the ability of RNA to fold into specific structures figures prominantly in many aspects of decoding the genome. One reason that individual bacterial promoters differ in DNA sequence is that the precise sequence determines the strength or number of initiation events per unit time of the promoter. Instead, the polymerase and DNA both undergo reversible structural changes that result in a more energetically favorable state.

Although RNA polymerase catalyzes essentially the same chemical reaction as DNA polymerase , there are some important differences between the two enzymes. They do not carry instructions for making a specific protein i.

Telomeres, protein synthesis vocabulary. Having considered transcription in bacteria, we now turn to the situation in eucaryotes, where the synthesis of RNA molecules is a much more elaborate affair. Bacterial RNA polymerase is a multisubunit complex. They do not carry instructions for making a specific protein i. We can view the series of conformational changes that takes place during transcription initiation as a successive tightening of the enzyme around the DNA and RNA to ensure that it does not dissociate before it has finished transcribing a gene.

The direction of transcription is determined by the promoter more Rabbit 3 days, and attainment contoh. However, RNA polymerase also excises many correct bases as part of the cost for improved accuracy. The RNA polymerase moves stepwise along the DNA, unwinding the DNA helix just ahead of the active site for polymerization to expose a new region of the template strand for complementary base -pairing. The DNA strands are pulled apart in the location of the gene to be transcribed, and enzymes create the messenger RNA from the sequence of DNA bases using the base pairing rules.

The choice of template strand for each gene is therefore determined by the location and orientation of the promoter. In eucaryotes, a transcription unit typically carries the information of just one gene , and therefore codes for either a single RNA molecule or a single protein or group of related proteins if the initial RNA transcript is spliced in more than one way to produce different mRNAs. These interactions, along more Eucaryotic transcription initiation must deal with the packing of DNA into nucleosomes and higher order forms of chromatin structure, features absent from bacterial chromosomes. The way in which RNA polymerases perform these tasks differs somewhat between bacteria and eucaryotes.

Makinos

The choice of template strand for each gene is therefore determined by the location and orientation of the promoter. The information in RNA, although copied into another chemical form, is still written in essentially the same language as it is in DNA—the language of a nucleotide sequence. The direction of transcription is determined by the promoter more Thus, in some respects, transcription termination seems to involve a reversal of the structural transitions that happen during initiation.
