Question

g EXCEPT _____. During elongation, RNA polymerase has three prominent channels, or grooves. These channels provide sites for all of the following EXCEPT _____. a site for the double-stranded DNA molecule a site for the exit of the diph

Answer 1

Answer:

A site for the exit of the diphosphates removed from the nucleotide triphosphates.

Explanation:

Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.

Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription.  RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand  and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.
