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).

The nucleus is the part of the eukaryotic cell that contains the cellâs 24 DNA molecules and is surrounded by a plasma membrane called the nuclear envelope. Transcription. Transcription is the process by which a cellâs nuclear DNA is transcribed into messenger RNA (mRNA). An enzyme called RNA polymerase starts at the opening sequence of a strand of DNA, called the promoter sequence, and then unwinds the DNA double helix little by little and transcribes that entire strand of DNA into mRNA.
