Albinism is a recessive trait characterized by an absence of pigment melanin responsible for skin and hair color. Actually, albinism is caused by a defect in gene for enzyme which synthesizes melanin. The central dogma of molecular biology explains that the sequence of DNA specifies the sequence of mRNA, which, further, specifies codes for the sequence of proteins. Since a gene is a segment of DNA, altered gene will cause altered mRNA which will cause altered protein. Thus, <span>defect in gene for enzyme which synthesizes melanin will cause the absence of melanin and consequently, albinism.</span>

Carbon dioxide and water join to form carbonic acid, which dissociates into hydrogen and bicarbonate.
The chemical compound of hydrogen, carbon, and oxygen is known as carbonic acid (H2CO3). It is created in trace amounts when carbon dioxide (CO2), its anhydride, dissolves in water.
Your body produces bicarbonate as a byproduct of metabolism, commonly known as HCO3. Your blood transports bicarbonate to your lungs, where it transforms into carbon dioxide and is inhaled. Your kidneys also aid in the control of bicarbonate. Your kidneys reabsorb and expel bicarbonate. This controls the pH, or acid balance, of your body.
