A) Tranesterifications are a type of chemical reaction.B) Bacteriophage λ integrase catalyzes the steps of tranesterification.C) Tranesterifications involve exchanging the phosphate group between two molecules.D) Tranesterifications involve transferring the phosphate group between two molecules.A) Tranesterifications are not a type of chemical reaction; they are a type of enzymatic reaction.B) Bacteriophage λ integrase does not catalyze the steps of tranesterification directly; instead, it catalyzes the transfer of a phosphate group from one molecule to another molecule.C) Tranesterifications involve exchanging the phosphodiester bond between two molecules.D) Tranesterifications involve transferring the phosphodiester bond between two molecules.
