X-ray Crystallography

• When ___ are beamed at a crystal, electrons
  diffract (bend) the X-rays, which causes a
  diffraction pattern. These patterns convert into
  visual maps.
• This process allows scientists to perceive
  molecules in ___
• This is a process used to help discover the
  structure of ___

5
DNA Fingerprinting

• ___ Fingerprinting is a method of identification
  that compares fragments of DNA.
• DNA is the ___material found within the cell
  nucleus.
• With the exception of identical ___, the complete
  DNA of each individual is unique.

6
DNA Fingerprinting Steps

• A DNA fingerprint is constructed by first
  obtaining a DNA ___ from body tissue or fluid.
• The sample is then cut into ___ using enzymes,
  and the segments are arranged by size using a
  process called gel electrophoresis.

7
DNA Fingerprinting

• The ___ are marked with probes and exposed on
  X-ray film, where they form a characteristic
  pattern of black bars the DNA fingerprint.
• If the DNA fingerprints produced from two
  different samples match, the two samples probably
  came from the _____.

8
DNA Fingerprinting

• DNA fingerprinting technology has helped
  scientists to discover the genetic ____ of many
  disease processes. Mapping the entire Human
  Genome (all of our DNA) has been one of the most
  massive scientific endeavors of all
  time. The complete
  human genome
  was
  completed in 2003.
• DNA fingerprinting helped
  advance ___
  
• science and paternity
  testing.

9
Microscopy (microscopes)

• ___ Microscopes use light and lenses to magnify
  small transparent objects.
• The ___ Microscope was developed due to the
  limitations of Light Microscopes. Light
  Microscopes are limited by the physics of light
  to magnify 1,000 times while Electron Microscopes
  can magnify up to 1,000,000 times.

Telescopes

• ___ and reflecting light telescopes collect light
  to view distant images.
• ___ telescopes collect radio waves to understand
  materials in space.
• ___ telescopes eliminate problems associated with
  looking through the atmosphere.

13
Computers

• ___ allow for the manipulation of large amounts
  of data.
• Computers help ___ machinery, tools, and
  processes.
• The Internet allows for ___ and widespread
  movement of data.

14
Medical imaging

• ___ are short wavelengths that penetrate tissue
  producing negative images of bones.
• ___ (Magnetic Resonance Imaging) is an imaging
  technique that uses magnets in medical settings
  to produce computer-enhanced images of the soft
  tissue inside of the human body.

15
Medical imaging

• ___Sonograms of a 61/2 month fetus in the whom of
  a mother.

16
Remote Sensing

• ___ (Global Positioning System) is a system able
  to show an exact position on the earth anytime,
  anywhere outside, and in any weather. The
  satellites transmit timed signals that can be
  detected by anyone with a GPS receiver.
• ___ and Sonar use electromagnetic waves to
  determine location, position, and movement of
  objects.

Remote Sensing

• ___ serve a variety of purposes from transmission
  of television signals to guidance and tracking
  systems for defense. For meteorologists,
  satellites provide a comprehensive view of the
  world's weather by observing weather and the
  environment on a scale not possible by other
  means.

Virtual Reality

• ___ is computer generated three-dimensional
  images that allow the user to interact with a
  virtual world (computer gaming).
• ___ mimic real world activities that may be
  dangerous or impossible to perform by a human
  (e.g. flight simulators).

  multiple lasers.
• Holograms are used on credit and bank cards for
  ___protection
