No. DNA (deoxyribonucleic acid) is a nucleic acid, composed of phosphate and sugar groups, with purine and pyrimidine bases. However, it does bind to proteins called 'histones'. Proteins are comprised of one or more chains of amino acids bonded together. Answer No. DNA or deoxyribonucleic acid is the genetic information carrier which is composed of basic unit called a nucleotide consisting of a pentose sugar (2' deoxyribose), nitrogenous base (purines - adenine and guanine; pyrimidines - cytosine and thymine) and a phosphate group. The DNA is compacted into lengths called chromosomes by interacting with histones and other proteins. DNA is mainly localized to nucleus as well as mitochondria and chloroplasts. When DNA mutates, a disease or other abnormality may result. A mutation is a change in the base sequence of DNA. A protein is made of amino acids. DNA consists of two sugar-phosphate backbones, spiraling around each other in a double helix, and joined to each other along their lengths by base-pairs. The base-pairs are adenine with thymine, and cytosine with guanine; none of these are amino acids.
