  2. chromosome
    cell structure that contains genetic information along strands of DNA
  3. DNA probe
    a molecule labeled with a radioactive isotope  dye, or enzyme that is used to locate a particular sequence or gene on a DNA molecule
  4. electrophroesis
    a method of separating molecules, such as DNA, according to their size and electrical charge using an electric current passed through a gel containing the samples
  5. gene
    segment of DNA in a chromosome that contains information used to produce a protein or an RNA molecule
  6. PCR
    (polymerase chain reaction( a method to repidily make multiple copies of a specific segment of DNA
  7. Restriction Enzyme
    a molecule that cuts a DNA molecule at a specific base sequence
  8. STR
    (short tandem repeat) tandem repeats of short DNA sequences with varying numbers of repeats found among individuals
  9. VNTR
    (variable number of tandem repeats) tandem repeats of a short DNA sequence with verifying numbers of repeats among individuals
  10. agglutination
    the clumping of molecules or cells caused by an antigen-antibody reactions
  11. antibody
    proteins secreted by white blood cells that attach to antigens
  12. antigen
    any foreign substance or cell in the body that reacts with antibodies
  13. Satellite spatter
    secondary drops formed when some blood breaks free from the main contact drop of blood
  14. Polymer
    a substance composed of long chains of repeating units
  15. nucleotide
    a molecule made up of sugar, phosphate group, and a nitrogenous base
  16. antiserum
    serum with antibodies used for injection into other animals to provide immunity to a specific disease
  17. DNA deoxyribonucleic
    deoxyribonucleic acid; main component of chromosomes and material transfers genetic characteristics in all life forms
  18. DNA fingerprint
    pattern of DNA fragments obtained by examining a person's unique sequence of DNA base pairs
  19. precipitin
    an antibody that reacts with its specific antigen to form an insoluble precipitate
  20. secretor
    a cell, tissue, or organ that creates a secretion
  21. serology
    the study of the chemistry of the blood
  22. serum
    component in blood that is neither a blood cell or a clotting factor
  23. mitochondria
    is a membrane-enclosed organelle found in most eukaryotic cell
  24. protein
    large biological molecules consisting of one or more chains of amino acids
  25. replication
    copying something
  26. RFLP
    restriction fragment length polymorphism, or RFLP (commonly pronounced “rif-lip”), is a technique that exploits variations in homologous DNA sequences
  27. Angle of Impact
    calculated from the measurement of the opposite side which is the width and the length is hypotenuse of the blood stain
  28. back spatter
    It is well known that gunshot wounding can produce fine droplets of blood spattered in a forward direction
  29. cast off
    Wet blood tends to move to the end of an object, where it pools; the drops after this
  30. HVIS
    caused by high veloctiy impact, small droplets; misting
  31. LVIS
    A bloodstain pattern that is caused by a low velocity impact/force to a blood source.
  32. MVIS
    drops caused by medium impact velocity
  33. parent drop
    the droplet from which satellite spatter originated
  34. spatter
    A spray or splash of something
  35. swipe pattern
    The transfer of blood from a moving source onto a unstained surface
  36. transfer pattern
    A bloodstain pattern created when a wet, bloody surface comes in contact with a second surface
  37. void
    Having no legal force or validity; null
  38. wipe pattern
    The event creating the original stain occurred before the event
  39. spine
    the pointed edges of a stain that radiate out to form the spatter
