Chapter 17 Opening Roadmap 2017 Pearson Education Inc Introduction to Transcription RNA Processing and Translation Proteins are the stuff of life A cell builds the proteins it needs from instructions encoded in its genome . Replication,. Transcription, & Translation. . DNA Replication. DNA Replication. . Before a cell can divide by . mitosis. or . meiosis. , it must first make a copy of its . chromosomes. .. The . 0. Chapter 15. Eukaryotic Gene Regulation. Almost all the cells in an organism are genetically identical.. Differences between cell types result from . differential gene expression. , the expression of different genes by cells with the same genome.. 7. 7 RNA Synthesis and Processing. Chapter Outline. Transcription in Prokaryotes. Eukaryotic RNA Polymerases and General Transcription Factors. Regulation of Transcription in Eukaryotes. RNA Processing and Turnover. Central Dogma of Biology. Information flows from . DNA .  RNA  Proteins. Think of it as exchanging money in a different country: proteins cannot be built directly from DNA. Three main processes involved:. DNA. RNA. PROTEIN. RNA and Transcription. RNA. R. ibo. n. ucleic . A. cid. another type of nucleic acid similar to DNA found in cells. also a polymer made of nucleotides. takes information from the nucleus to the rest of the cell. Understanding:. Gene expression is regulated by proteins that bind to specific base sequences in DNA . The environment of a cell and of an organism has an impact on gene expression. Nucleosomes help to regulate transcription in eukaryotes. 3.5.1: Compare the structure of RNA and DNA.. 3.5.1: Compare the structure of RNA and DNA.. IB Question: .

A eukaryotic transcription initiation complex consists of RNA polymerase II, . five. general transcription factors (GTFs), and a 20-subunit complex called Mediator (or . Srb. /Med). The CTD of RNA polymerase II anchors Mediator to the polymerase. Mediator allows RNA polymerase II to communicate with transcriptional . .. The length of the transcription bubble is about 12 to 14 . bp. , but the length of the RNA–DNA hybrid within the bubble is only 8 to 9 . bp. . As the enzyme moves along the template, the DNA duplex reforms.
