- Consider this list (below) of steps involved in transcription. These steps are out of order. TRANSCRIPTION: 1. mRNA travels through a nuclear pore and enters the cytoplasm 2. the mRNA polymerase attaches at the start of a specific gene 3. RNA polymerase reads the gene surface4. a transcription factor bonds to a promoter site5. DNA molecule is unwound 6. a complimentary mRNA is produced What is the correct order of this transcription?arrow_forwardExplain how ncRNA uses complementary base pairing with DNA to affect gene expression.arrow_forwardPlease explain: Transcription-what is it and what does it involve?
