DNA transcription is a process that involves transcribing genetic information from DNA to RNA. The transcribed DNA message, or RNA transcript, is used to produce proteins.
The two major steps in creating a protein are transcription and translation. Transcription creates an mRNA molecule, using a DNA sequence as a template. DNA and mRNA are similar, although certainly not identical, molecules. An mRNA sequence is essentially a copy of a DNA sequence with the thymines replaced by uracil. The production of mRNA is known as transcription which means copying. Creating a protein from an mRNA sequence is known as translation because the structure of a protein is very different from that of mRNA. Proteins are sequences of amino acids, not bases. The information in the mRNA is converted to a new form â it is translated. A sequence of bases is translated into a sequence of amino acids.
