words only definitions & notes
  1. DNA chip
    a microchip that holds DNA probes that form half of the DNA double helix and can recognize DNA from samples being tested
    DNA chip, also called a DNA microarray or biochip, is a technology developed in the late 1990’s that enables scientists to study hundreds or thousands of genes at once.
  2. biochip
    a microchip that uses tiny strands of DNA to latch onto and quickly recognize thousands of genes at a time; intended for use in a biological environment
    DNA chip, also called a DNA microarray or biochip, is a technology developed in the late 1990’s that enables scientists to study hundreds or thousands of genes at once.
  3. deoxyribonucleic acid
    (biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information
    These instructions are stored in DNA (deoxyribonucleic acid), the chief substance of chromosomes.
  4. multicellular
    consisting of many basic structural and functional units
    Even the simplest multicellular organisms have thousands of genes.
  5. DNA
    material that carries genetic information in a cell
    DNA chip, also called a DNA microarray or biochip, is a technology developed in the late 1990’s that enables scientists to study hundreds or thousands of genes at once.
  6. gene
    part of DNA controlling physical characteristics and growth
    DNA chip, also called a DNA microarray or biochip, is a technology developed in the late 1990’s that enables scientists to study hundreds or thousands of genes at once.
  7. chromosome
    a threadlike strand of DNA that carries genes
    These instructions are stored in DNA (deoxyribonucleic acid), the chief substance of chromosomes.
  8. biologist
    a scientist who studies living organisms
    However, biologists know that the thousands of genes that make up the genome (entire set of genes) of an organism interact in complex ways.
  9. nylon
    a synthetic fabric
    DNA chips are often similar in appearance to microscope slides and are typically made of glass, silicon, nylon, or plastic.
  10. organism
    a living thing that can act or function independently
    Genes carry the chemical instructions that determine an organism's traits.
  11. genome
    the full DNA sequence of an organism
    However, biologists know that the thousands of genes that make up the genome (entire set of genes) of an organism interact in complex ways.
  12. grid
    a pattern of regularly spaced horizontal and vertical lines
    A single chip may contain tens of thousands of individual DNA spots per square centimeter (0.16 per square inch), arranged in an ordered array (grid pattern).
  13. silicon
    a tetravalent nonmetallic element
    DNA chips are often similar in appearance to microscope slides and are typically made of glass, silicon, nylon, or plastic.
  14. synthetic
    a compound made artificially by chemical reactions
    Synthetic, single-stranded sequences of DNA called oligonucleotides, which may or may not contain genes, can also serve as probes.
  15. scientist
    a person with advanced knowledge of empirical fields
    DNA chip, also called a DNA microarray or biochip, is a technology developed in the late 1990’s that enables scientists to study hundreds or thousands of genes at once.
  16. protein
    an organic compound essential to living cells
    In the past, scientific studies of genes have focused on identifying individual genes and the products, such as proteins, that they produce.
  17. microscope
    magnifier of the image of small objects
    DNA chips are often similar in appearance to microscope slides and are typically made of glass, silicon, nylon, or plastic.
  18. chemical
    produced by reactions involving atomic or molecular changes
    Genes carry the chemical instructions that determine an organism's traits.
  19. computer
    a machine for performing calculations automatically
    Computers track the gene or DNA sequence represented by each spot.
  20. acid
    a sour water-soluble compound with a pH of less than 7
    These instructions are stored in DNA (deoxyribonucleic acid), the chief substance of chromosomes.
