Predict a Possible Effect of Deleting the Enhancers Region of the Polymerase

Question

Predict a possible effect of deleting the enhancers region of the polymerase I gene.
A)reduced transcription of ribosomes
B)reduction in the production of most hnRNAs
C)reduction in the amount of rRNA made
D)reduction in the production of Rpb1
E)reduction in the production of Rpb2

Accepted Answer

The enhancer region of the polymerase I gene is important for the transcription of ribosomal RNA (rRNA) genes. Deleting this region would lead to a reduction in the amount of rRNA made, which would ultimately affect ribosome assembly and protein synthesis in the cell. It would not directly affect the production of other types of RNA or RNA polymerase subunits.
