    Transcription is the process by which information encoded in DNA is copied into messenger RNA (mRNA) for eventual translation into protein. Transcription is generally thought of as proceeding in three steps.
    1. RNA polymerase attaches to the DNA template strand at specific nucleotide sequences called promoter regions. It is often helped in this process by other proteins called transcription factors, which aid in unwinding the DNA helix and in the attachment of RNA to the promoter.
    2. The elongation step is next. In this step, RNA makes a copy, through base-pairing, of the DNA template strand. The RNA strand will contain U in place of T and there is not thymine in RNA. The single strand of RNA that is produced is mRNA.
    3. Termination. When the RNA polymerase reaches the termination sequence of the DNA template it releases the ...

    Solution Summary

    This articles describes transcription and translation in full detail. It also explains how to interpret and use the genetic code to determine the protein sequence that results from translation of a given mRNA. This text document would make a good basis for writing an essay on transcription and translation.
