Blood tests, unlike urinalysis, detect the presence illicit drugs, not inactive drug metabolites. In general, THC only remains detectable in the blood of cannabis consumers for a few hours (though low, residual levels may be detected in chronic smokers for up to 12-24+ hours if more sensitive technology is used).
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.
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.
