During maturation process of some RNA molecules, formation of a 2'–5' phosphodiester bond takes place. Following statements are made about this phenomenon.
(A) Spliceosome mediated removal of intronic sequences occurs through the formation of a 2'–5' phosphodiester bond.
(B) Removal of group II introns occurs through the formation of 2'–5' phosphodiester bond.
(C) Enzymatic removal of introns from the yeast tRNA precursors involves 2'–5' phosphodiester bond formation.
(D) RNaseP mediated 5'-end maturation of tRNA precursors involves formation of a 2'–5' phosphodiester bond.
Which one of the following combinations of the statements is a true representation
In group II introns the reaction pattern is similar except for the nucleophile in the first step, which in this case is the 2’ -hydroxyl group of an A residue within the i...
