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 copying of genetic information from the form of DNA to the form of RNA. Remember that RNA is a single-stranded molecule; it doesn't have a complementary strand like DNA does. It's only half a ladder, or a single strand of nucleotides. In order to make the RNA strand, we only need one of the original DNA strands.
