A urine drug test can detect marijuana as soon as 2 to 5 hours after use. However, the bigger question is how long will it still be detected with a THC urine drug test. The length of time marijuana is detected in urine depends on the amount used, frequency of use and the user's weight and body fat.
Transcription & Translation: Transcription (Basic). Transcription is the process by which the information in DNA is copied into messenger RNA (mRNA) for protein production. Transcription begins with a bundle of factors assembling at the promoter sequence on the DNA (in red).Here, two transcription factors are already bound to the promoter.ranscription & Translation: Transcription (Basic).

Transcription is the first stage of the expression of genes into proteins. In transcription, a mRNA (messenger RNA) intermediate is transcribed from one of the strands of the DNA molecule. The RNA is called messenger RNA because it carries the 'message' or genetic information from the DNA to the ribosomes, where the information is used to make proteins. Transcription may be broken into five stages: pre-initiation, initiation, promoter clearance, elongation and termination.
