In the three dimensional structures obtained of RNA polymerase lI bound to template DNA. RNA and incoming substrate NTPS Komberg and colleagurs concluded that there are two nucleotide binding sites, called the entry (E) site and acceptor (A) site. Which of the tollowing statements correctly cescribes features of the E or A site? Select one: O a. A nucleotide bound to the A site is not correctly positioned for pticsphodiester bond formation. O b. None of these correctly describes featurcs of these sites O C. The correct nucleotide tu be next added to the growing RNA trascript would first bind to the Asite and then later bindd to the E site O d. The A site will birid all nuclcotides regardless of whether or not they can correctly bae-pair to the template DNA, O e. Anucleotide bound tu the E site is not correctly positioned for phosphordiester bord formation

In the three dimensional structures obtained of RNA polymerase ll bound to template DNA. RNA and incoming substrate NTPS Komberg and colleagurs concluded that
there are two nucleotide binding sites, called the entry (E) site and acceptor (A) site. Which of the tollowing statements correctly cescribes features of the E or A site?
Select one:
O a. A nucleotide bound to the A site is not correctly positioned for pticsphodiester bond formation.
O b. None of these correctly describes featurcs of these sites
OC. The correct nucleotide to be next added to the growing RNA trascript would first bind to the Asite and then later bindd to the E site
O d. The A site will birid all nuclcotides regardless of whether or not they Can correctly bae pair to the template DNA,
O e. Anucleotide bound tu the E site is not correctly positioned for phosphorliester bord formation
