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 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.The process relies on Watson-Crick base pairing, and the resultant single strand of RNA is the reverse-complement of the original DNA sequence.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).
