Science 1
What does DNA stand for?
Deoxyribonucleic Acid.
What is the function of DNA?
DNA stores the genetic information of an organism.
What does genetic information determine?
Genetic information determines how an organism looks, behaves, and functions.
What is forensic science?
Forensic science is the application of science to law, the judicial system.
What is a DNA profile?
A DNA profile is a genetic fingerprint or a specific DNA pattern.
What are some sources of DNA that can be found in a crime scene?
Blood, hair, saliva, teeth, bone, and tissues and cells.
What is DNA used for in Forensic Science?
It's used for the identification of criminals by analyzing the biological evidence in a crime scene. It can also clear anyone who was wrongly convicted of a crime.
What are DNA profiles used for?
DNA profiles are used to identify individuals based on their genetic information.
What else is DNA profiling called?
DNA profiling is also called DNA fingerprinting.
What can DNA profiling be used for?
DNA profiling can be used for things like recognizing the origin of a bodily sample found in a crime scene, revealing family relations, and identifying disaster victims.
When was DNA profiling first used for forensics and human identification?
DNA profiling was first used for forensics and human identification in the early 1980's.
Who discovered DNA profiling?
British geneticist Sir Alec John Jeffreys discovered DNA profiling.
What does DNA technology in the criminal justice system ensure?
It ensures truth and fairness.
What are the four DNA bases?
Adenine, guanine, cytosine, and thymine.
What does VNTR stand for?
VNTR stands for variety number tandem repeats.
What were the first criminal cases solved by the power of DNA?
The murder cases of Lynda Mann and Dawn Ashworth were the first criminal cases solved by the power of DNA.
How was the method Sir Alec John Jeffreys discovered first used?
This method was first used in an immigration case when determining a British boy's genetic relationship to his family with Ghanaian origins.
What are some DNA techniques used in forensics? (Any 2 techniques)
Some DNA techniques are Polymerase Chain Reaction (PCR), Mitochondrial DNA, Short Tandem Repeats (STR), Y-Chromosome Analysis, and Restriction Fragment Length Polymorphism.
What are Tandem Repeats?
A tandem repeat is a sequence of DNA bases like adenine, guanine, cytosine, and thymine, that are repeated in a chromosome in a pattern order.
What is DNA profiling?
DNA profiling is the process of collecting, processing, and analyzing someone's VNTR.
