FRSC 2007- FINAL EXAM(Correctly solved)
Mitochondrial DNA, characteristic, where can we find these, who are they inherited (both) from
correct answers Mitochondrial DNA - found in mitochondria
(mitochondria are in the cytoplasm and are the site of cells' energy production)
mitochondrial DNA is inherited exclusively from the mother (single lineage)
5 Layers epidermis correct answers The epidermis is the most superficial layer of the skin and
provides the first barrier of protection from the invasion of substances into the body.
The epidermis is subdivided into five layers or strata:
stratum corneum (horny layer)
stratum lucidum (hyalin layer)
stratum granulosum (granular layer)
stratum spinosum (spinous layer)
stratum basale (basal layer)
Different types of ammunition (from the firearm lecture) and differences from those correct
answers bullets and cartridge ?
Oblique lighting, what is it used for? correct answers Oblique lighting is commonly used when
photographing impressions, tool marks and certain types of fingerprints. (latent)
How many bones in the human body correct answers The adult human skeleton is made up of
206 bones
(A baby's body has about 300 bones at birth)
Fingerprint patterns classification and patterns (be able to recognize the different patterns, no
trick ones) correct answers whorl, loop arch
Differences between latent and patent fingerprint impression? correct answers Patent prints are
impressions of prints usually transferred using some type of fluid or chemical, like blood or
paint.
Latent prints, on the other hand, are formed by the natural oils in one's skin and transferred by
the friction of touch.
DNA- spell, know what it is, describe it correct answers Deoxyribonucleic acid (abbreviated
DNA) is the molecule that carries the genetic information for the development and functioning of
an organism. DNA is made of two linked strands that wind around each other to resemble a
twisted ladder — a shape known as a double helix
(-Two types of DNA:
1. Mitochondrial DNA - found in mitochondria
2. Nuclear DNA - found on chromosomes in the nucleus of
a cell)
Fingerprint powders, most common one, uses for each correct answers Black Fingerprint Powder
is typically used on non-porous light-coloured surfaces
, Granular PowdersCarbon-All types of surfaces
Metal Flake Powders-All types of surfaces
luminescent under special radiationMulti-colored surfaces
Serial number restoration correct answers Law enforcement agencies submit firearms and other
items to the BCA Forensic Science Services that have obliterated serial numbers, serial numbers
that have been ground, filed or removed by other means.
Forensic scientists can use physical and chemical techniques to restore or enhance altered
characters. Restoring a serial number can provide law enforcement agencies with information
about a firearm or other item and may offer a lead in an investigation.
Tool mark category correct answers There are three major categories of tool marks: indentations
marks, abrasion marks, and cutting marks
Class characteristics of footwear, fingerprints, and bullets correct answers In footwear, the class
characteristics are the design features placed on the outsole by the manufacturer, such as logos,
brand name and tread pattern
Fingerprints are an individual characteristic. Since fingerprints are a random growth pattern on
an individual's skin, and they do not change over time, no two people have identical fingerprints.
On bullets, the class characteristics are the rifling specifications of the barrel from which the
bullet was fired. These include caliber, number of lands and grooves, direction of twist of the
lands and grooves, and widths of the lands and grooves
Flexion creases correct answers What are the three flexion creases?
The three major palmar creases: Radial longitudinal (I), Proximal transverse (II), and Distal
transverse (III
Regions of the palm correct answers Carpal region.
Dorsal region of hand.
Palm; Palmar region.
Thenar eminence.
Hypothenar eminence.
Metacarpal region.
Digiti manus.
Blood stain patterns and classification correct answers Bloodstains are classified into three basic
types: passive stains, transfer stains and projected or impact stains
Locard exchange principle correct answers Locard's Exchange Principle states that with contact
between two items, there will be an exchange of microscopic material
Info about tire tread and footprint impression correct answers 17.
When it comes to the Tire cycle rotation (sites, lists, treads, Class vs accidental characteristics)
correct answers What are 3 class characteristics that can be found in the analysis of tires?
design/tire tread design, physical size, and wear
Mitochondrial DNA, characteristic, where can we find these, who are they inherited (both) from

(mitochondria are in the cytoplasm and are the site of cells' energy production)
