Promoters for eukaryotic mrna synthesis
WebTranscription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein. The human body contains many transcription factors. So does the body of a bird, tree, or fungus! Transcription factors help ensure that the right genes are expressed in the right cells of the body, at ... WebThe prokaryotes, which include bacteria and archaea, lack membrane-bound nuclei and other organelles, and transcription occurs in the cytoplasm of the cell. In both prokaryotes and …

Did you know?
WebThe correct answer is d. transcription, RNA processing, nuclear export, translation. In eukaryotic cells, protein synthesis begins with the process of transcription. During transcription, an enzyme called RNA polymerase binds to the DNA strand at a specific sequence called the promoter. The RNA polymerase then unzips the DNA and uses one … http://www.biology.arizona.edu/molecular_bio/problem_sets/mol_genetics_of_eukaryotes/07t.html

Similar to the class notes (Intro to Genetics), a segment of DNA (shown below) contains a promoter segment (the first 9 base pairs), a ribosome binding segment (the next 6 base pairs), and a segment that codes for protein synthesis which is started by the rest of the base pairs.
