Solution

$(1)$ The primary transcripts contain both the exons and introns and are non-functional. Hence it is subjected to a process called splicing where introns are removed and exons are joined in a defined order.

$(2)$ It gives passage to $RNA$ polymerase moving from promotor to structural gene i.e. it control. activity of structural gene.
