Animation Assessment Question 4 of 5 The transcription bubble is the region where: O A. RNA polymerase is allowing the DNA double helix to reform after RNA is synthesized B. RNA polymerase is opening the DNA double helix as it proceeds. C. RNA polymerase is opening the DNA double helix as it proceeds and allowing the DNA double helix to re-form after RNA is synthesized. D. RNA polymerase is opening the DNA double helix as it proceeds, adding nucleotides to the growing RNA chain using one strand of DNA as a template, and allowing the DNA double helix to re-form after RNA is synthesized. O E. RNA polymerase is adding nucleotides to the growing RNA chain using one strand of DNA as a template SUBMITExplanation / Answer
1) Answer: D - RNA polymerase is opening the DNA double helix as it proceeds, adding nucleotides to the growing RNA chain using one strand of DNA as a template, and allowing the DNA double helix to re-form after RNA is synthesized.
Transcription bubble is formed on the DNA unwinding downstream. It contains RNA polymerase, DNA and the new RNA formed which in turn leads to re-form of DNA double helix.
2) Answer: A - general TFs and RNA polymerase II.
PIC includes RNA polymerase II and six general transcription factors namely TFIIA, TFIIB, TFIID, TFIIE and TFIIF. these protein complexes are necessary for transcription of protein coding genes in eukaryotes and archaea.
3) Answer: E - U1 snRNP; 3'-OH; 5'
