In an attempt to locate genes\' promoters, researchers conduct deletion mutation

Question

In an attempt to locate genes' promoters, researchers conduct deletion mutations and then measure the expression levels of the respective transcripts. Deletions were made in an expmranscription to locate the promoter for the SS-RNA gene and the results are shown below. The start site (TSS) is numbered +1 t designed etion Level of for high transcription(-forno expression, + for low levels of expression levels of expression) 45 through-+ +1 to +47 +1 to +63 +50 to +80 + 80 to +12° | 24. From the data above, it can be concluded that the transcription factor binding sites for RNA polymerase III are located A) Upstream of the coding region (5' to the coding region) B) In the region between +50 and +80 within the coding region C) In the region +80 to +120 within the coding region D) Downstream of the coding region E) In the region-45 through -1 upstream of the coding region. 25. You are studying a biochemical pathway. Preliminary results suggest that this pathway is subject to end-product repression. This pathway is therefore most likely to be aln) pathway A) anabolic B) catabolic C) constitutive D) induced E) unregulated

Explanation / Answer

Answer -

24.B - In the region between +50 and +80 within the coding region.
