BIO206H5 Study Guide - Comprehensive Final Exam Guide - Dna, Rna, Protein
Document Summary
Scanned by camscanner: prokaryotic chromosome and gene structure, bacteria have a single circular chromosome. Most of the information about bacterial transcription, translation and. Figure 1 on the next page shows the locations of the genes on the single circular chromosome. In this tutorial we will focus on transcription. As a storage medium, dna must have certain properties: the molecule must be able to carry information, the molecule must be readable. It is no use putting information into a storage medium if the information cannot be retrieved: the molecule must be stable and secure, the information must be passed from generation to generation. Thus the molecule must be able to remain essentially unchanged for many generations. Rna molecules read and interpret the information in dna. The role of rna is for information transfer and information decoding. Rna molecules are key players in the reactions that turn information into useful work.
