D- 1- initiation , termination , elongation
Note - the initiation process involve binding of polymerase enzyme to promoter gene followed by elongation of the rna transcript with adding nucleotide after that release factor arrive and relieve the newly formed transcript .

RNA polymerase releases the DNA template. Initiation Elongation Termination A process called clearance or escape. The RNA polymerase holoenzyme binds to the promoter A process called clearance or escape. Reaching a terminator sequence causos formation of phosphodiester bonds to stop. The RNA polymerase holoenzyme is formed. Once bound to the promoter, RNA polymerase begins to unwind the DNA. New nucleotides are added to the 3' end of the growing RNA transcript. The RNA-DNA hybrid within the transcription bubble dissociates New...

Which of the following is true for transcription in E. coli, but not for transcription in humans? a. Transcription requires RNA polymerase to add nucleoside triphosphates to the 3' end of the growing transcript (RNA). b. Transcription does not require primers during initiation or elongation. c. Transcription requires promoters, which have mostly adenines and thymines. d. Transcription produces polycistronic mRNA that includes several coding regions within one transcription unit.

Question 8 1 pts What do you think would be the most likely outcome if you shortened the spacer region of a promoter from 17-mer to 7-mer? No transcription initiation Initiation would occur, but no elongation Transcription would occur normally There would be no termination of transcription The alpha subunits of RNAP would be required for successful initiation Question 9 1 pts During transcription the first RNA nucleotide is synthesized at what position relative to the promoter? 0-10 +1 Upstream...
