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).

What is the shape of a DNA molecule? The double helix shape of DNA molecules consists of two rails and steps that link the rails together. DNA nucleotides line up so that the sugar and phosphate molecules create two long backbones, which form the rails of DNA's double helix structure.
