The Seville harbour, located about 80 kilometres (50 miles) from the Atlantic Ocean, is the only river port in Spain. Seville is also the hottest major metropolitan area in Europe, with summer average high temperatures of above 35 Â°C.
Three different types of RNA exist, mRNA or messenger RNA, tRNA or transfer RNA, and rRNA or ribosomal RNA. Protein Synthesis Cells store and use coded information. The genetic information stored in DNA is used to direct the synthesis of the thousands of proteins that each cell requires.The chemical and structural properties of DNA are the basis for how the genetic information that underlies heredity.DNA is encoded in the sequence of nitrogenous bases which directs the formation of proteins in the cell.he chemical and structural properties of DNA are the basis for how the genetic information that underlies heredity. DNA is encoded in the sequence of nitrogenous bases which directs the formation of proteins in the cell.
In the last couple of class periods, we have discussed the replication of the cell's DNA and the mechanisms by which the integrity of the genetic information is maintained. We now turn to the fascinating process by which information in DNA is used by the cell to direct the synthesis of RNAs and proteins. The various cell types in a multicellular organisms owe their distinctive phenotypes to differences in the proteins made in each kind of cell.
