Problem: What happens during the initiation step of DNA transcription?1. The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand.2. A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.3. A ribosome attaches to the initiation codon of a completed mRNA strand.4. RNA polymerase moves along the template strand of the DNA creating an mRNA strand
