genomics ge·no·mics (jē-nō'mĭks)
The study of all of the nucleotide sequences, including structural genes, regulatory sequences, and noncoding DNA segments, in the chromosomes of an organism.
|genomics (jə-nō'mĭks) Pronunciation Key
The scientific study of genomes.
The field of science that studies the entire DNA sequence of an organism's genome. The goal is to find all the genes within each genome and to use that information to develop improved medicines as well as answer scientific questions. (See also proteomics.)
study of the structure, function, and inheritance of the genome (entire set of genetic material) of an organism. A major part of genomics is determining the sequence of molecules that make up the genomic deoxyribonucleic acid (DNA) content of an organism. The genomic DNA sequence is contained within an organism's chromosomes, one or more sets of which are found in each cell of an organism. The chromosomes can be further described as containing the fundamental units of heredity, the genes. Genes are transcriptional units, those regions of chromosomes that under appropriate circumstances are capable of producing a ribonucleic acid (RNA) transcript that can be translated into molecules of protein.
