Transcription of the mouse dihydrofolate reductase gene proceeds unabated through seven polyadenylation sites and terminates near a region of repeated DNA.
We observed equimolar transcription throughout the 35-kilobase mouse dihydrofolate reductase structural gene. Transcription termination occurred within a discrete region (900 base pairs) located 1 kilobase beyond the last of seven functional polyadenylation sites and near a repetitive DNA sequence element. The results imply that a distinct genetic signal may be associated with the process of transcription termination.
