click and drag on elements in order
put the events of transcription in order, with the earliest event at the top.
instructions
rna polymerase reaches the termination signal, releases the new mrna, and leaves the dna.
the dna helix rewinds into its double - helical shape.
rna polymerase binds to the genes promoter.
rna polymerase moves along the dna strand, adding complementary nucleotides to a growing mrna chain.
a section of the dna unwinds and pulls apart, exposing part of the base sequence.

Explanation:

Transcription starts with RNA - polymerase binding to the promoter. Then DNA unwinds, followed by RNA - polymerase adding nucleotides to the mRNA chain. After reaching the termination signal, it releases mRNA and leaves. Finally, the DNA rewinds.

Answer:

1. RNA polymerase binds to the gene's promoter.
2. A section of the DNA unwinds and pulls apart, exposing part of the base sequence.
3. RNA polymerase moves along the DNA strand, adding complementary nucleotides to a growing mRNA chain.
4. RNA polymerase reaches the termination signal, releases the new mRNA, and leaves the DNA.
5. The DNA helix rewinds into its double - helical shape.
