Ribonucleic acid (RNA) is a key nucleic acid in transcription and translation. RNA is like DNA except that:. 3.5.1: Compare the structure of RNA and DNA.. 3.5.1: Compare the structure of RNA and DNA.. IB Question: . Compare the structure and composition of DNA with RNA. . [4]. both are polymers of nucleotides / both nucleic acids;. DNA directs the activities of the cell by controlling the proteins the cell produces.. This determines what the cell becomes, what it synthesizes, and how it functions. Gene Protein occurs in 2 steps Transcription and Translation. Chapters 16 and 17.

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.
