RNA polymerase performs two proofreading functions on that growing transcript Choose the correct statement regarding the proofreading functions

a.in the pyrophosphorolytic editing catalyze the removal of an incorrectly inserted ribonucleotide, by reincorporation of PPi

b.In the pyrophosphorolytic editing the polymerase backtracks by one or more nucleotides and cleaves the RNA product

c.In hydrolytic editing, the polymerase backtracks by one or more nucleotides and cleaves the RNA product

d.In hydrolytic editing, catalyze the removal of an incorrectly inserted ribonucleotide, by reincorporation of Ppi

Choose the correct statement

a. Hexokinases IV remains sequesters in the nucleus in case of high F-6-P and high ATP

b. Hexokinases IV remains sequesters in the cytoplasm in case of high F-6-P and high ATP

c. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is not ATP4- but the MgATP2- complex.

d. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is MgATP4- but not the MgATP2- complex.
