RNA polymerase is the enzyme responsible for the transcription of the DNA. It reads one strand of the DNA and transcribed into the RNA. It adds the nucleotide to the 3' end of the growing chain of the RNA. It starts the process by binding to the promoter region of the gene. The enzyme adds nucleotide not ribonucleotide.
The answer is C.

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 occurs ONLY in eukaryotic cells and NOT in prokaryotic cells? RNA polymerase binds to the DNA template at the promotor sequence of the gene RNA polymerase is capable both of unwinding and separating the DNA helix - hence displaying part of the DNA template for transcription - and of catalyzing the formation of phosphodiester bonds. RNA polymerase pairs up Uracil (U) in the elongating RNA strand with Adenine (A) in the DNA template RNA polymerase pairs...

1. Which of the following statements concerning transcription of bacterial mRNA is not true? Bacterial mRNA must have intron material removed before it can be used in the process of protein translation.* Energy necessary for transcription is provided by the breaking of phosphate bonds carried by ribonucleotide triphosphates (rNTPs). A sigma factor recognizes the promoter site sequences on the DNA strand during transcription. A guanine-rich sequence on the template DNA molecule causes the growing RNA strand to loop and detach.
