Arrange the events taking place during transcription in order: i) the pre-rna undergoes processing ii) rna polymerase moves downstream, unwinding the dna iii) rna polymerase binds to the promoter iv) rna transcript is released and polymerase detaches from the dna v) polymerase initiates rna synthesis at the start point on the template strand

RNA polymerase binds to the promoter

Polymerase initiates RNA synthesis at the start point on the template strand

RNA polymerase moves downstream unwinding the DNA

RNA transcript is released and polymerase detaches from the DNA

The pre-RNA undergoes processing

Explanation:

The promoter is the specific DNA sequence that serves as a binding site for RNA polymerase. The enzyme RNA polymerase recognizes the promoter sequence and binds to it to begin the process of RNA synthesis. The process of RNA synthesis begins at the start site where the process of the unwinding of DNA duplex is initiated.

The unwinding separates the two DNA strands at the start site where RNA polymerase begins the process of synthesis of the new RNA strand. The newly formed RNA strand and RNA polymerase are released from the template strand after the termination of the process.

In eukaryotes, the primary RNA transcript undergoes the process of splicing of introns, the addition of poly-A tails and 5' cap which in turn transform it into the mature mRNA.
