Introduction
DNA profiling is a technique used to identify individuals based on their DNA. It has become an essential tool in forensic investigations, paternity testing, and genetic research. The DNA profiling gizmo quiz is designed to help students understand the basics of DNA profiling. In this article, we will provide the answer key to the DNA profiling gizmo quiz.
Question 1
What is the purpose of DNA profiling?
Answer: The purpose of DNA profiling is to identify individuals based on their DNA.
Question 2
What is PCR?
Answer: PCR stands for Polymerase Chain Reaction. It is a technique used to amplify DNA strands.
Question 3
What is gel electrophoresis?
Answer: Gel electrophoresis is a technique used to separate DNA fragments based on their size.
Question 4
What is a restriction enzyme?
Answer: A restriction enzyme is an enzyme that cuts DNA at specific sequences.
Question 5
What is a DNA fingerprint?
Answer: A DNA fingerprint is a unique pattern of DNA fragments that can be used to identify individuals.
Question 6
What is the difference between VNTRs and STRs?
Answer: VNTRs (Variable Number Tandem Repeats) are longer DNA sequences that are repeated multiple times. STRs (Short Tandem Repeats) are shorter DNA sequences that are repeated multiple times.
Question 7
What is CODIS?
Answer: CODIS (Combined DNA Index System) is a database of DNA profiles used by law enforcement agencies to match DNA samples to individuals.
Question 8
What is mitochondrial DNA?
Answer: Mitochondrial DNA is DNA that is found in the mitochondria of cells. It is inherited only from the mother.
Question 9
What is Y-chromosome DNA?
Answer: Y-chromosome DNA is DNA that is found in the Y-chromosome. It is inherited only from the father.
Question 10
What is genetic genealogy?
Answer: Genetic genealogy is the use of DNA testing to determine familial relationships and ancestry.
Conclusion
The DNA profiling gizmo quiz is a useful tool for students to learn about DNA profiling. By understanding the basics of DNA profiling, students can appreciate the importance of this technique in various fields. We hope that this answer key has helped you better understand the DNA profiling gizmo quiz.
