Genetic Mapping And Sequencing

GENE MAPPING AND THE SEQUENCING OF THE HUMAN GENOME: Learning the structure and function of human genes and chromosomes, which, all taken together, are called the human genomes. Researchers plan first to map the genome, then to sequence areas of special interest, and finally to sequence (or decipher the genetic letters contained in) all 3 to 3.5 billion base pairs that comprise our genome. Gene mapping and sequencing will initially provide detailed knowledge about where important genes are located and how they function. Application of this new knowledge

will be diagnostic:

Tests will be developed for large numbers of diseases, and these tests will then be able to be used in newborn screening, prenatal diagnosis and carrier screening. At the same time, it may help scientists and clinicians to deveop ways to correct, or at least compensate for, at least some genetic defects.
