Unit 4 DNA Evidence Study Guide

Front

What is DNA Fingerprinting?

Back

A technique used to identify individuals based on their unique DNA patterns.

Front

What is Gel Electrophoresis?

Back

A method used to separate DNA fragments by size using an electric field.

Front

Why do DNA pieces move in Gel Electrophoresis?

Back

DNA pieces move towards the positive charge because DNA is negatively charged.

Front

What is the role of a PCR Machine in DNA analysis?

Back

It amplifies small segments of DNA to create millions of copies for analysis.

Front

What is a Restriction Enzyme?

Back

An enzyme that cuts DNA at specific sequences, creating fragments of varying lengths.

Front

What is the first step in creating a DNA fingerprint?

Back

Cut the DNA into different sized pieces using restriction enzymes.

Front

What does it mean when we say DNA is unique to each individual?

Back

Each person's DNA sequence is different, making their DNA fingerprint unique.

Front

What is the purpose of comparing DNA fingerprints?

Back

To determine if two DNA samples come from the same individual.

Front

What is the significance of the term 'fingerprint' in DNA Fingerprinting?

Back

It signifies that just like a physical fingerprint, DNA fingerprints are unique to each individual.

Front

What is the final step in DNA fingerprinting?

Back

Compare the DNA fingerprints to find a match.
