The ESI #640 DVA adapter is plugged into a digital meter and the voltage range is normally set to about 400V DC for most testing. Trigger, pulser, and timer-base outputs use a lower voltage range.
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.he pre-messenger RNA thus formed contains introns which are not required for protein synthesis. The pre-messenger RNA is chopped up to remove the introns and create messenger RNA (mRNA) in a process called RNA splicing (Figure 5).
Transcription.   Transcription is the production of the first draft of mRNA, using the base sequence of the template strand of DNA to determine the base sequence of the R â¦ NA. This RNA will include any introns, which will later be cut out; this is called RNA editing. 3 people found this useful. Answered. In Genetics.
