D.N.A. can be found in the follicle/root of a hair.
What is "Chain of Custody?"
"Chain of Custody" is the documented and unbroken transfer of evidence.
What do D.N.A. and R.N.A. stand for?
D.N.A. stands for Deoxyribonucleic Acid. R.N.A. stands for Ribonucleic Acid.
What is Locard's Exchange Principle?
Locard's Exchange Principle states that when a person or object comes into contact with another person or object. cross contamination occurs.
What are the four components of blood?

What is the "Medulla" of a hair?
The "Medulla" is the central core of a hair fiber.
What is Mass?
Mass is the amount of atoms in something.
List the following things from smallest to largest:
D.N.A., Genes, Chromosomes
The correct listing is:
Genes, Chromosomes, D.N.A.
Name the five different types of evidence we learned about.
Class Evidence, Individual Evidence, Trace/Biological Evidence, Direct Evidence, Indirect/Circumstantial Evidence.
Where in blood can you find someone's D.N.A.?
You can find someone's D.N.A. in their White Blood Cells.
What is "Keratin?"
"Keratin" is a type of fibrous protein that makes up the majority of the cortex of a hair.
What is Volume?
Volume is the amount of space taken up by a given object.
What is the purpose of Helicase in the D.N.A. Replication Process?
Helicase unwinds/unzips the Double Helix.
Can you define "Primary Crime Scene" and "Secondary Crime Scene"?
The Primary Crime Scene is where the crime took place. Secondary Crime Scenes are locations other than the primary scene where related evidence is found.
What is the protein in Red Blood Cells that carries oxygen?
The protein in Red Blood Cells that carries oxygen is called "Hemoglobin."
What is a "Comparison Microscope?"
A "Comparison Microscope" is a compound microscope that allows the side-by-side comparison of samples, such as hair or fibers.
What is Density?
Density is how much Mass there is per unit of Volume.
What is the name of the point where the Double Helix splits? Additionally, what are the names of the top and bottom strands of an unzipped Double Helix?
The splitting point of a Double Helix is called the "Replication Fork." The top strand is the "Leading Strand" and the bottom strand is the "Lagging Strand."
Can you name and draw at least two of the four ways investigator walk around/search a crime scene?
Spiral, Grid, Linear, and Quadrant.
What is the shape of a Red Blood Cell? Why does it have that shape?
A Red Blood Cell is shaped like a bowl because it doesn't have a Nucleus.
What types of evidence can hair be?
Hair is always considered Trace Evidence. It is considered Class Evidence unless the follicle/root is intact, in which case it is individual evidence.
What is "Neutron Activation Analysis?"
"Neutron Activation Analysis" is a method of analysis that determines the composition of elements in a sample.
Who discovered D.N.A.? Additionally, who was one of the first scientists to help learn D.N.A.'s purpose?
D.N.A. was discovered by Friedrich Miescher in 1869. Rosalind Franklin disproved the popular "Triple Helix Theory" and helped to learn the real purpose of D.N.A..
Can you list all of the Seven S's in order?
