Question

The following table provides data concerning the effects of various deletions in a eukaryotic gene coding for 5S - rRNA on the ability of this gene to be transcribed by RNA polymerase III. What do these data tell you about the probable location of the promoter for this particular 5S - rRNA gene? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used. These data suggest that the promoter for the 5S - rRNA gene is located between nucleotides and, because deletions that include nucleotides within this stretch the transcription of the 5S - rRNA gene. Note that this type of promoter lies within the gene - that is, it is located from the startpoint.

Explanation / Answer

These data suggest that the promoter for the 5S rRNA gene is located between nucleotides +10 through +63 and +80 through +123, because deletions that include within this stretch prevent the transcription of the 5S rRNA gene. Note that this type of promoter lies within the gene - that is, it is located downstream from the start point.
