Briefly outline the impact of the absence of thiamin on cell division
Thiamin plays an important role in the synthesis of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and triglycerides. To aid in energy synthesis, thiamin acts as a coenzyme, meaning that an enzyme will not function unless thiamin is present. Without thiamin acting as a coenzyme, the enzymes that make DNA and RNA cannot work, and protein synthesis is halted. As a result, cell division is impeded because the genetic material (DNA and RNA) cannot be replicated.
