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 ___

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.

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. DNA Fingerprinting Steps

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 _____. 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 DNA fingerprinting helped advance ___ science and paternity testing.

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.

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.

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.

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

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.

Radar and Sonar (show movie clip)

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).

Simulations (show movie clip)

Holograms ___ are three- dimensional images produced by multiple lasers. Holograms are used on credit and bank cards for ___protection
