What is DNA Fingerprinting?

Back

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

Front

Why does DNA fingerprinting work?

Back

No two people, except identical twins, have exactly the same DNA.

Front

What is Gel Electrophoresis?

Back

A method used to separate DNA fragments based on their size, often used in DNA fingerprinting.

Front

What is the primary use of DNA Fingerprinting?

Back

Identifying individuals in forensic science, paternity testing, and genetic relationship analysis.

What is NOT a use for DNA Fingerprinting?

Back

Finding the likelihood of inheriting a genetic disorder.

What role do primers play in DNA fingerprinting?

Back

Primers are short sequences of nucleotides that provide a starting point for DNA synthesis during PCR.

Front

What is PCR (Polymerase Chain Reaction)?

Back

A technique used to amplify small segments of DNA, making millions of copies for analysis.

Front

What is the significance of STRs (Short Tandem Repeats) in DNA fingerprinting?

Back

STRs are regions of DNA that are highly variable among individuals, making them useful for identification.

Front

How can DNA fingerprinting be used in paternity testing?

Back

By comparing the DNA profiles of a child and potential parents to identify biological relationships.
