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 »

The repeating subunits that make up DNA are called nucleotides. A nucleotide is an organic molecule that helps provide the structure for both DNA and RNA strands. More »

Nucleotides are the sub-units that make up DNA, and are made up of even smaller sub-units. The differences between these sub-units result in the unique base pairs that record genetic information and make up genes. More »

DNA sequencing is a technique used to determine the exact sequence of nucleotides in a DNA sample. Electrophoresis, a method for separating DNA fragments, is used when the DNA differs in length by only one base. DNA samp... More »

DNA is a long molecule composed of two chains of smaller molecules called nucleotides, each which contain a region of nitrogen called the nitrogenous base, a carbon-based sugar molecule called deoxyribose and a region of... More »

Both DNA and RNA are macromolecules that consist of long chains of nucleotides. Both contain the specific nucleotide bases adenine, guanine and cytosine, although the fourth base differs between DNA and RNA. Both molecul... More »
