Unit 3 Test Review

Front

What is the science behind DNA technology?

Back

The science behind DNA technology is well-established and involves techniques such as DNA sequencing, polymerase chain reaction (PCR), and genetic engineering.

Front

What size droplets are created by high velocity blood splatter?

Back

High velocity blood splatter creates droplets of less than 1 mm in size.

Front

Who can be a bloodstain analyst?

Back

A bloodstain analyst can be law-enforcement or laboratory staff.

Front

What does blood pattern analysis involve?

Back

Blood pattern analysis involves examination of size, shape, distribution, and overall appearance; reconstruction of the crime scene; and determination of consistency of scientific evidence with the accounts of the crime.

Front

Did scientists begin using the physics of blood-spatter analysis after the O.J. Simpson murder trial?

Back

False; scientists were already using blood-spatter analysis before the O.J. Simpson murder trial.

Front

Define DNA technology.

Back

DNA technology refers to the methods used to analyze and manipulate DNA, including cloning, sequencing, and genetic modification.

Front

What is the significance of blood pattern analysis in forensic science?

Back

Blood pattern analysis helps reconstruct crime scenes and understand the events that led to bloodshed.

Front

What are the key components of blood pattern analysis?

Back

Key components include the size, shape, distribution, and overall appearance of bloodstains.

Front

What is the role of a forensic scientist in bloodstain analysis?

Back

A forensic scientist analyzes bloodstains to provide evidence that can support or refute accounts of a crime.

Front

What factors can affect the shape of blood droplets?

Back

Factors include the angle of impact, the surface texture, and the velocity of the blood.
