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).
Structure of DNA. The molecular structure of DNA forms a double helix with a backbone of each strand of the helix consisting of a repeating ...sugar-phosphate-sugar-phosphate... polymer; the sugar is deoxyribose.tructure of DNA.

DNA: Double Helix. The secondary structure of DNA is actually very similar to the secondary structure of proteins. The protein single alpha helix structure held together by hydrogen bonds was discovered with the aid of X-ray diffraction studies. The X-ray diffraction patterns for DNA show somewhat similar patterns.
