Question

Enter the appropriate word or words into each blank to complete the following statements about RNA synthesis. A. DNA sequence that directs binding of RNA polymerase for transcription of a downstream gene is called a direction B. Synthesis of DNA and RNA molecules always proceeds in the C. During transcription of eukaryotic genes, intron sequences are removed from the new RNA molecule, while are stitched together during the process called D. Mature eukaryotic messenger RNAS (MRNA8) have a 5'- and 3'-end structures known as a and that are absent in prokaryotic mRNAs. E. In addition to using different substrates (rNTPs rather than dNTPs), RNA polymerases differ from DNA polymerases in that they do not require a de novo synthesis of RNA and do not have for error correction. to initiate activity, which is responsible
