Molecular Staging

Molecular Staging is addressing this demand with a portfolio of products and services based on technologies that are transforming the detection and measurement of both proteins and nucleic acids.

  • genetic-disorderIf an organism carries a harmful genetic mutation, it can still survive and sometimes even function normally if something in the organism’s environment can compensate for the genetic defect. In this situation, the organism may not appear mutant at all (in other words, though its genotype is mutant, its phenotype is normal – click here for more definitions). Sometimes missing substances normally made by the product of the mutant gene can be provided, or substances normally removed by the product of the mutant gene can be limited in the diet.

  • chromosomesThere are two copies of each chromosome in every cell of an organism. One set of chromosomes comes from the mother and one comes from the father. The chromosomes shown to the right have been spread out on a slide to help scientists called cytogeneticists to tell them apart. Read the rest of this entry »

  • fly_antenna1Scientists discovered the existance of genes that determine body plan by analyzing bizarre aberrations in body form that resulted from mutations in fruit flies. For example, Ed Lewis and his colleagues observed fruit flies with legs growing from the head in place of antennae (for real!). They found that a single mutation in a gene could make this happen.

  • inheritenceHow are genes passed from parent to child? Genes are composed of a chemical called DNA. The many, many genes needed for all the biological functions of an organism are found linked together in the cell on extremely long pieces of DNA, called chromosomes. Each human cell (except sperm and egg cells) has two copies of each chromosome, one from the mother and one from the father. Read the rest of this entry »
