DNA Analysis
Unlike nuclear DNA, this type of DNA is circular in shape and inherited exclusively from a person's mother
mitochondrial DNA
This is the outermost layer of the hair shaft, made of overlapping scales that protect the inner layers
Cuticle
This toxicological discipline is responsible for testing postmortem tissues and fluids to see if drugs or poisons contributed to a victim's death
Postmortem Investigation
These are the types of glass cracks that form first, originating from the impact site and radiating outward like wheel spokes
Radial
This laboratory technique uses an electrical current to separate DNA fragments according to their size
DNA Electrophoresis
Without a root attached, a strand of hair cannot identify a specific individual, meaning it is classified as this type of evidence
Class Evidence
According to the Drug Classification Act, substances like heroin fall under this specific group because they have a high potential for abuse and no accepted medical use
Schedule 1
These secondary circular fractures form around the point of impact on the same side as the striking force
Name a good source of DNA.
Blood, skin cells, and hair roots are excellent sources of biological evidence
This innermost layer of the hair shaft can form different structural patterns, such as continuous or fragmented lines
Medulla
According to toxicology rules, any substance can be toxic depending heavily on this primary factor
Dosage
Forensic scientists can determine the sequence of multiple impacts because a newer fracture line will always do this when it hits an existing fracture line
It will be stopped by the existing line
This is the acronym for the FBI's national database system used to store and compare DNA profiles from across the country
CODIS
To get individual DNA evidence from a hair sample, an investigator must recover this specific structure
Hair Root
Which of these does NOT affect substance toxicity?
A. Dosage
B. Time of Day
C. Genetics
D. Body Weigth
B. Time of Day
When a bullet penetrates a pane of glass, this specific side of the hole will be smaller and cleaner
Entry hole
These are the two specific locations inside a human cell where DNA can be extracted for analysis
Nucleus and Mitochondria
Because hair grows slowly and absorbs chemicals from the bloodstream, forensic scientists can analyze it to find a long-term evidence of:
Toxins, drugs, or poisons
According to the BAC chart, this would be the approximate Blood Alcohol Concentration (BAC) of a 100-pound female who consumed 6 drinks
0.36
Which type of glass is found in car windows (NOT windshield)
Tempered
