DNA finger printing

What is DNA fingerprinting?

• DNA fingerprinting is a method used to determine a person's blood type.

• DNA fingerprinting is a technique used to analyze fingerprints left at a crime scene.

• DNA fingerprinting is a process used to identify individuals by analyzing their hair samples.

• DNA fingerprinting is a technique used to identify individuals by analyzing their unique DNA patterns.

What does PCR stand for?

Which technique is used to analyze DNA samples in forensic science?

• Hair analysis

• Blood typing

• DNA profiling

• Fingerprint analysis

What is the purpose of DNA fingerprinting in forensic science?

• To determine the age of a person.

• To identify individuals and establish biological relationships.

• To analyze the chemical composition of a substance.

• To study the behavior of animals in their natural habitat.

What is the main advantage of PCR in DNA analysis?

• Ability to analyze multiple DNA samples simultaneously

• Amplification of specific DNA sequences

• Faster analysis time compared to other methods

• Increased sensitivity in detecting DNA samples

What is the role of restriction enzymes in RFLP analysis?

• Restriction enzymes join DNA fragments together to create longer strands for analysis.

• Restriction enzymes amplify DNA fragments to increase the amount of genetic material for analysis.

• Restriction enzymes modify DNA sequences to introduce mutations for analysis.

• Restriction enzymes cut DNA at specific recognition sites to create fragments for analysis.

How does DNA fingerprinting help in solving crimes?

• By examining the physical characteristics of the suspects.

• By conducting interviews with witnesses and suspects.

• By comparing DNA profiles of suspects with DNA evidence from the crime scene.

• By analyzing the fingerprints left at the crime scene.

What are the steps involved in PCR?

• Denaturation, Annealing, Extension

• Inactivation, Attachment, Elongation

• Separation, Hybridization, Replication

• Melting, Binding, Amplification

How is RFLP analysis different from PCR in DNA profiling?

• RFLP analysis involves cutting and separating DNA fragments, while PCR amplifies specific regions of DNA.

• RFLP analysis is a faster method for DNA profiling compared to PCR.

• RFLP analysis can analyze a larger amount of DNA samples compared to PCR.

• RFLP analysis uses gel electrophoresis to separate DNA fragments, while PCR does not involve gel electrophoresis.
