The location where the GCR-complex attaches to the DNA is called the glucocorticoid response element (GRE). The GRE is located approximately 250 base-pairs upstream of the growth hormone (GH) gene. Name the enzyme that catalyses transcription. Name the transcription product, molecule S, and describe the processing that molecule S undergoes before it exits the nucleus.

Answer

The transcription product, molecule S, is pre-mRNA. Before it exits the nucleus, molecule S undergoes several processing steps:

Removal of introns (intron removal) or joining of exons.
Addition of a methyl cap at the 5' end.
Addition of a poly-A tail at the 3' end.
