DNA contains the genetic information necessary for the synthesis of RNA and thereby all proteins necessary for the cell to function. RNA is a sequence of nucleotides that contain information for the synthesis of proteins. Deoxyribose is a sugar present in the nucleotides of DNA. Proteins are also provide  information. 

Nicotinamide adenine dinucleotide is a co-enzyme. It is required for the fundamental biological process that make life possible. It is called dinucleotide because it consists of two nucleotides joined together through their phosphate groups.

The three major antioxidant vitamins are beta-carotene, vitamin C and vitamin E. Beta carotene is an antioxidant that gets converted to vitamin A and plays a very important role in health. It's responsible for the red, yellow, and orange coloration of some fruits and veggies.

Vitamins are accessory food factors, which are required in small quantity for controlling metabolism and body functioning. Vitamins are of two types- fat soluble (A, D, E, K) and water soluble (B and C). Vitamins like minerals are not digested but directly absorbed from ingested food. They play role in metabolism and growth.

Deficiency diseases are diseases which are caused due to deficiency of a critical nutrient in diet. The nutrient cannot be synthesized in body and must be present in diet. Scurvy, Rickets and Beriberi are some of the common deficiency diseases in man. Scurvy is caused due to deficiency of vitamin C. The common symptoms are bleeding gums, loose teeth, anaemia, painful and swollen joints, delayed healing of wound, and emaciation. Beriberi is caused due to deficiency of vitamin B$ _{1}$. Its symptoms are loss of appetite. Fatigue, muscle atrophy paralysis, mental confusion, cardiac oedema. Rickets is caused due to deficiency of vitamin D and minerals like phosphorous and calcium in children. Its symptoms are defective mineralization or calcification of bones potentially leading to fractures and deformity.

• A vitamin is an organic molecule that is an essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism. 
• Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.
• Best food sources of vitamin B:     Whole grains (brown rice, barley, millet)

• Sprouting is the natural germination process by which seeds or spores put out shoots, plants produce new leaves or buds, or other newly developing parts experience further growth. Hence, A good source of vitamins of B groups is Germinated seeds.

In the large intestine, water is absorbed into the blood as the waste materials move through the colon. The symbiotic bacteria such as E. coli and Streptococcus faecalis, normally residing in the healthy human colon, feed on protein contents of chyle breaking them into amino acids which are absorbed into the blood. The colon bacteria also synthesize vitamins B1, B2, biotin, folic acid and K which are absorbed. They also convert bile pigments into brown pigments which give colour to faeces.
