Looking to the future, it is likely we will see a reduction in the number of car trips Americans take and a rise in the number of trips they take by foot, bicycle, public transit or train.

It is called transcription because there is no change in language; information is encoded in the same way, through the sequence of bases in both DNA and RNA. Transcription is mediated by DNA-dependent, RNA polymerase, an enzyme that builds an RNA molecule using a DNA molecule.We will return to consider the process of transcription and its regulation later when we come to Genomes and Genes (reading 26) and Regulatory networks (reading 27).hen the ribosome reaches the end of the region of the RNA that encodes the polypeptide (defined by a stop codon), it is released, disassembles and is ready to start another cycle. Key translation accessory factors are the transfer RNAs or tRNA. These are small, L-shaped RNAs.
