There is disclosed a process for the isomerization of a branched diene which comprises passing the branched diene in the vapor phase over a boron phosphate catalyst, the improvement comprising a catalyst which has an initial molar ratio of P/B of less than 1.0 but more than 0.6.
Answers. Best Answer: The spontaneous isomerization of a nitrogen base to an alternative hydrogen-bonding form, possibly resulting in a mutation. Reversible shifts of proton position in a molecule. Bases in nucleic acids shift between keto and enol forms or between amino and imino forms. Base substitutions are generally caused by changes in the way that nucleotides base pair. One way this occurs is through tautomeric shifts.
