DNA has a negative charge due to the negative charge of its phosphate component. The other two components of DNA consist of a 5-carbon sugar and a nitrogen base. More »

DNA has a slightly negative charge due to the presence of phosphate groups found in the sugar-phosphate backbone of a DNA molecule. In addition to a phosphate group, each nucleotide of a DNA molecule features a nitrogen-... More »

DNA, or deoxyribonucleic acid, is genetic material that exists in nearly all living organisms, including humans. Any organism with nucleus-based cells has DNA. It is the building blocks forming an organism, and the DNA c... More »

DNA is made of repeating units called nucleotides. The four nucleotides in DNA are adenine, cytosine, guanine and thymine. Adenine binds with thymine, and guanine binds with cytosine. More »
