Clindamycin is used to treat a wide variety of bacterial infections. It is an antibiotic that works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for virus infections (e.g., common cold, flu).

DNA is composed of a sugar-phosphate backbone and nitrogenous bases. In double-stranded DNA, the nitrogenous bases pair up. Adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). The shape of DNA resembles that of a spiral staircase.
