Which vitamin is essential for DNA synthesis and neural tube development?

Explanation:
Folate is essential for DNA synthesis and neural tube development. It drives one-carbon metabolism that builds thymidine and purines, the building blocks of DNA, which is crucial during rapid cell division in early development. Adequate folate prevents neural tube defects by supporting proper neural tube formation in the embryo. You’ll find folate in leafy greens, legumes, and fortified grains, and many women take folic acid supplements before and during pregnancy to reduce risk of defects. The other vitamins listed contribute to energy metabolism and general health, but they don’t play the direct, critical role in DNA synthesis and neural tube formation that folate does.
