- Front
- Back
Arch |
a fingerprint pattern in which the ridge pattern originates from one side of the print and leaves from the other side |
|
core |
a center of a loop or whorl |
|
delta |
a triangular ridge pattern with ridges that go in different directions above and below a triangle |
|
fingerprint |
an impression left on any surface that consists of patterns made by the ridges on a finger |
|
latent fingerprint |
a hidden fingerprint mad visible through the use of powders or other techniques |
|
loop |
a fingerprint pattern in which the ridge pattern flows inward and returns in the direction of the origin |
|
minutiae |
the combination of details in the shapes and positions of ridges in fingerprints that make each unique; also called ridge characteristics |
|
patent fingerprint |
a visible fingerprint that happens when fingers with blood, ink, or some other substance on them touch a surface and transfer the pattern of their fingerprint to that surface |
|
plastic fingerprint |
a three-dimensional fingerprint mad in soft material such as clay, soap, or putty |
|
ridge pattern |
the recognizable pattern of the ridges found in the end joints of fingers that form lines on the surfaces of object in a fingerprint. they fall into three categories: arches, loops, and whorls |
|
ten card |
a form used to record and preserve a person's fingerprints |
|
whorl |
a fingerprint pattern that resembles a bull's-eye |

|
|
allele |
an alternate form of a gene; for example, a gene for human hair color may have alleles that cause red or brown hair |
|
chromosome |
a cell structure that contains genetic information along strands of DNA |
|
DNA fingerprint |
pattern of DNA fragments obtained by examining a person's unique sequence of DNA base pairs (also called DNA profiling) |
|
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 |
|
electrophoresis |
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 |
|
gene |
segment of DNA in a chromosome that contains information used to produce a protein or an RNA molecule |
|
PCR |
(polymerase chain reaction) a method used to rapidly make multiple copies of a specific segment of DNA; can be used to make millions of copies of DNA from a very small amount of DNA |
|
restriction enzyme |
a molecule that cuts a DNA molecule at a specific, base sequence |
|
STR |
(short tandem repeat) tandem (next to each other) repeats of short DNA sequences (two to five vase pairs) with varying numbers of repeats found among individuals |
|
VNTR |
(variable number of tandem repeats) tandem repeats of short DNA sequence (9 to 80 base pairs) with varying numbers of repeats among individuals |
