Basics of Blood
This liquid component of blood is responsible for transporting blood cells, waste products, and antibodies.
What is plasma?
This type of stain is created by the force of gravity alone
What is a passive stain?
Blood type AB contains these two markers on red blood cells.
What are A and B markers?
This molecule is referred to as the "code of life" because it tells cells how to produce proteins
What is DNA?
This experiment measures the diameter of blood droplets at different heights.
What is blood droplet analysis?
These cells, known for their bright red colour, carry oxygen around the body.
What are red blood cells?
These stains are produced when a bloody surface comes into contact with another surface
What are transfer stains?
This blood type has neither A nor B markers.
What is type O?
This type of DNA profile is unique to each person, except for identical twins.
What is a full DNA profile?
The formula used in droplet analysis calculates this value for each height.
What is the average diameter?
These cells make up about 1% of blood and play a vital role in protecting the body from infection.
What are white blood cells?
Blood spatter that forms straight-line patterns can result from this type of motion of an object.
What is cast-off?
These components of blood are used in DNA analysis to narrow down suspect pools.
What are white blood cells?
This is the shape of DNA
What is double helix (spiral)?
This household item is used as a filter in DNA extraction from a strawberry.
What is a coffee filter?
These blood components are responsible for coagulation and help stop bleeding by forming a platform at injury sites.
What are platelets?
The study of blood spatter patterns can help answer this questions about a crime scene
What is forensic blood pattern analysis?
Combining the ABO and Rh systems results in this many possible blood types.
What is 8?
This is the percentage of DNA that is unique
What is 0.1%?
In strawberry DNA extraction, ice-cold rubbing alcohol is used to perform this process.
What is precipitation?
This property of blood allows droplets to remain spherical in the air due to interactions between plasma molecules.
What is surface tension?
The size and shape of these stains can indicate the direction and force of impact.
What are impact stains?
The most common blood type in Ireland
What is O positive?
This is the full name of DNA
What is deoxyribonucleic acid?
Crushing a strawberry in a sandwich bag begins this initial step of DNA extraction.
What is breaking open the cells?
