|
a fingerprint pattern in which the ridge pattern originates from one side of the print and leaves from the other side |
arch |
|
|
a center of a loop or whorl |
core |
|
|
a triangular ridge pattern w/ ridges that go in different directions above and below a triangle |
delta |
|
|
an impression left on any surface that consists of patterns made by the ridges on a finger |
fingerprint |
|
|
a hidden fingerprint made visible through the use of powders or other techniques |
latent fingerprint |
|
|
a fingerprint pattern in which the ridge pattern flows inward and returns in the direction of the orgin |
loop |
|
|
the combination of details in the shapes and positions of ridges in fingerprints that make each unique; also called ridge characteristics |
minutiae |
|
|
a visible fingerprint that happens when fingers w/ blood, ink, or some other substance on them touch a surface and transfer the pattern of their fingerprint to that surface |
patent fingerprint |
|
|
a three- dimensional fingerprint made in soft material such as clay, soap, or putty |
plastic fingerprint |
|
|
the recognizable pattern of the ridges found in the end joints of fingers that form lines on the surface of objects in a fingerprint. they fall into three categories: arches, loops, and whorls |
ridge pattern |
|
|
a form used to record and preserve a person's fingerprints |
ten card |
|
|
a fingerprint pattern that resembles a bull's-eye |
whorl |
|
|
an alternate form of a gene; for example, a gene for human hair color may have alleles that cause red or brown hair |
allele |
|
|
a cell structure that contains genetic info along strands of DNA |
chromosome |
|
|
pattern of DNA fragments obtained by examining a person's unique sequence of DNA base pairs (also called DNA profiling) |
DNA fingerprint |
|
|
a molecule labeled w/ a radioactive isotope, dye, or enzyme that is used to locate a particular sequence or gene on a DNA molecule |
DNA probe |
|
|
a method of separating molecules, such as DNA, according to their size and electrical charge using an electrical current passed through a gel containing the samples |
electrophoresis |
|
|
segment of DNA in a chromosome that contains information used to produce a protein or an RNA molecule |
gene |
|
|
(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 |
PCR |
|
|
a molecule that cuts a DNA molecule at specific, base sequence |
restriction enzyme |
|
|
(short tandem repeat) tandem (next to each other) repeats of a short DNA sequences (two to five base pairs) w/ varying numbers of repeats found among individuals |
STR |
|
|
(variable number of tandem repeats) tandem (next to each other) repeats of a short DNA sequence (9 to 80 base pairs) w/ varying numbers of repeats among individuals |
VNTR |
