Answer: True.

Megaloblastic anaemia is a medical condition in which the bone marrow which produce red blood cells produces very large, abnormal, unstructural cells called megaloblasts. This result from disruption in DNA synthesis. It is a nutritional defficiency which is due to inability of the body to absord nutrients. This is caused by deficiency of vitamin B12 and folate. The symptoms include dizziness, increase heart rate, e. t. c
