Asked Nov 2, 2019
All of the following vitamins play a critical role in DNA synthesis EXCEPT:
  vitamin B12.
  vitamin B6.

Expert Answer

Step 1

Folate, thiamine, and vitamin B12 play a critical role in DNA synthesis except vitamin B6. Vitamin B6 (pyridoxine) forms enzyme group of decarboxylases and transaminases, that involve in metabolism of nerve tissues.

Step 2

Folate (vitamin B9) are essential for the synthesis of DNA. Its derivatives are involved in the biosynthesis of purines and pyrimidines. Formyl folate is required for the biosynthesis of inosine monophosphate (precursor to GMP and AMP). They are also required for the modification of DNA and RNA.

Step 3

Thiamin (vitamin B1) is involved in DNA and RNA production. Its active form is a coenzyme known as thiamine py...
