Forensic Science

A:

Creating your own DNA fingerprint helps you to learn about DNA. This process takes about an hour to put together and overnight to set. You need a DNA sample, beakers, a laboratory, restriction enzymes, a gel tray, an electrophoresis apparatus, buffer solution, a staining sheet and a staining tray.

  • Why Is Forensic Science so Important?

    Q: Why Is Forensic Science so Important?

    A: Forensic science is important because it aids in establishing the guilt or innocence of potential suspects. Forensic evidence is also useful for linking crimes, which establishes the patterns of crimes and also narrows the number of probable suspects.

  • Q: What Are the Differences Between DNA Fingerprinting and Regular Fingerprinting?

    A: Regular fingerprinting methods conduct tests and make records of finger and thumb prints of an individual, while DNA fingerprinting tests the deoxyribonucleic acid of a person, which is located within the nucleus of all cells in the body, states The Tech Museum of Innovation. During DNA fingerprinting, scientists analyze the genetic material to determine the differences in DNA between individuals.

  • Q: What Are Some Different Forms of Biometric Identification?

    A: Biometric devices are security measures that use an element of a person's unique biological properties to identify him, rather than a more easily copied identifier such as a password. Biometric devices typically use a component of biology that is difficult to use fraudulently, such as fingerprints, handprints, a voice pattern or the retina of the eye. It is fairly safe to assume that if a person has the correct biometrics, he is using the correct identity.

  • Q: What Are Some Facts About Fossils?

    A: Fossils are the remains of plant or animal life that were buried for millions of years until they finally turned to stone. Most fossils found today are from creatures that lived in the sea, as these had a much better chance of being buried before they were destroyed.

  • Q: How Do You Create a Hypothesis About Fingerprinting?

    A: To create a hypothesis for fingerprinting, investigators ask questions based on what they know about the specific topic in question and come up with a statement that can be proven through an experiment. Then, based on their prior observations, they develop a statement to test. For example, an experiment on whether fingerprints are hereditary might read "If fingerprints are hereditary, then testing with a fingerprinting kit will show that all members of a family have similar fingerprints."

  • What Is a Comparison Microscope?

    Q: What Is a Comparison Microscope?

    A: A comparison microscope is a specialized microscope that allows for a side-by-side comparison of different materials. Invented by Calvin Goddard in the 1920s, these microscopes are often used today by the FBI and other law enforcement to determine the similarities of objects such as hairs and fired ammunition.

  • What Is the Most Common Fingerprint Pattern?

    Q: What Is the Most Common Fingerprint Pattern?

    A: Fingerprints patterns are of three types: arches, loops and whorls, and loops are the most common pattern, being found in 65 to 70 percent of all fingerprints. In this pattern, ridges or curved lines enter from one side of the finger, form a loop and exit from the same side.

  • Q: How Do You Obtain DNA for DNA Fingerprinting?

    A: To obtain DNA for DNA fingerprinting, a sample of cells from skin, hair, blood, saliva or semen is collected. The white blood cells from the sample are broken open using detergent, and then the usable DNA is separated from all the other cellular material. Subsequently, the extracted DNA is cut into smaller pieces using restriction enzymes.
