| Motif | Three-dimensional structure of gene product (protein) with known or implied function. eg DNA binding membrane spanning. A motif is often inferred from a cDNA sequence. |
| Protein | A large molecule composed of one or more chains of amino acids in a specific order; the order is determined by the base sequence of nucleotides in the gene coding for the protein. Proteins are required for the structure, function, and regulation of the bodys cells, tissues, and organs, and each protein has unique functions. Examples are hormones, enzymes, and antibodies. |
| Deoxyribonucleic acid (DNA) | The molecule that encodes genetic information. DNA is a double-stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T). In nature, base pairs form only between A and T and between G and C; thus the base sequence of each single strand can be deduced from that of its partner. |
| Complementary DNA (cDNA) | DNA that is synthesized from a messenger RNA template that corresponds to expressed sequences of genomic DNA. The term complementary DNA also may refer to DNA that is complementary to a particular DNA sequence. The single-stranded form is often used as a probe in physical mapping. |
| DNA sequence | The relative order of base pairs, whether in a fragment of DNA, a gene, a chromosome, or an entire genome. See base sequence. |
