Eukaryotic promoter
WebEukaryotes assemble a complex of transcription factors required to recruit RNA polymerase II to a protein coding gene. Transcription factors that bind to the promoter are called basal transcription factors. These basal factors are all called TFII (for transcription factor/polymerase II) plus an additional letter (A–J).

WebApr 9, 2024 · A scientist splices a eukaryotic promoter in front of a bacterial gene and inserts the gene in a bacterial chromosome. Would you expect the bacteria to transcribe the gene? The mouse genome includes one gene and two pseudogenes for cytoplasmic thymidine kinase. WebThe core promoter in eukaryotes is usually composed of which two features? Transcriptional start site and TATA box Proteins that play a role in initiating transcription in eukaryotes include general transcription factors RNA polymerase II mediators general transcription factors and RNA polymerase II
Eukaryotic promoters are so complex in structure that the DNA tends to fold back on itself which helps to explain how many physically distant DNA sequences can affect transcription of a given gene. The TATA-binding protein binds the TATA box and helps in the subsequent binding of the RNA polymerase. See more The core promoter region is located most proximal to the start codon and contains the RNA polymerase binding site, TATA box, and transcription start site (TSS). RNA polymerase will bind to this core promoter region … See more Further upstream from the core promoter you will find the proximal promoter which contains many primary regulatory elements. The proximal promoter is found approximately 250 base pairs upstream from the TSS and it … See more The final portion of the promoter region is called the distal promoter which is upstream of the proximal promoter. The distal promoter also … See more WebA promoter is a regulatory region of DNA located upstream (towards the 5' region) of of a gene, providing a control point for regulated gene transcription. The promoter contains specific DNA sequences that are recognized by proteins known as transcription factors.
Weba) The rate of elongation during DNA replication is slower in prokaryotes than in eukaryotes. b) Prokaryotic chromosomes have histones, whereas eukaryotic chromosomes do not. c) Prokaryotic chromosomes have a single origin of replication, whereas eukaryotic chromosomes have many. d) Prokaryotes produce Okazaki … WebMay 14, 2024 · There are several methods used by eukaryotes. Altering the rate of transcription of the gene. This is the most important and widely-used strategy. However, eukaryotes supplement transcriptional regulation …
WebThe majority of genes are organized individually in eukaryotes, but are organized as operons in prokaryotes; the complexity of eukaryotic development requires that transcription be more coordinated and integrated than in prokaryotes; combinatorial control of gene expression is more common in eukaryotes.
