Question

Quizplus · Accepted Answer

Vitamin B12 plays a crucial role in cell division by aiding in the synthesis of DNA, which is essential for the growth and repair of tissues. This function is closely related to the role of folate, as both vitamins are involved in the methylation of nucleic acids. Vitamin B12 is required to activate an enzyme that converts homocysteine to methionine, which is then used to make SAM (S-adenosylmethionine), a molecule that is involved in numerous methylation reactions, including the methylation of DNA. Without adequate vitamin B12, the proper synthesis of DNA cannot occur, leading to impaired cell division and a range of health problems.
