Some Events that May Occur during Transcription 1. RNA polymerases detach. 2. DNA polymerases detach. 3. DNA polymerases proofread. 4. RNA double helix is unzipped. 5. DNA double helix is unzipped. 6. DNA double helix forms again. 7. mRNA is built in the 3' to 5' direction. 8. mRNA is built in the 5' to 3' direction. 9. RNA ligase fuses the Okazaki fragments. 10. RNA polymerase binds to the sense strand. 11. DNA polymerase binds to the sense strand. 12. RNA polymerase binds to the antisense strand. 13. DNA polymerase binds to the antisense strand. Listed in sequence, the events involved in DNA transcription numbered above are __, __, __, __ and __.

Step 1
- DNA transcription involves the synthesis of RNA from a DNA template. The key enzymes involved are RNA polymerase, not DNA polymerase, and the process does not involve RNA ligase or Okazaki fragments, which are specific to DNA replication. Show more…

Place the following in the proper sequence for Transcription. A. RNA polymerase encounters a stop signal and releases the completed mRNA transcript. B. The mRNA transcript is processes to eliminate non-coding regions and facilitate recognition. C. RNA polymerase builds a single stranded RNA copy of the gene, called the mRNA transcript. D. The DNA helix unwinds so RNA polymerase can bind. E. The DNA rewinds to its original double-helix shape. F. RNA polymerase recognizes the promoter site, binds to one strand of the DNA, and begins to read the gene.
