What is DNA Fingerprinting?

Back

DNA Fingerprinting is a technique used to create a picture from the results of gel electrophoresis, revealing the unique patterns in a person's DNA.

Front

What does PCR stand for?

Back

PCR stands for Polymerase Chain Reaction, a method used to amplify DNA.

Front

What is a restriction enzyme?

Back

A restriction enzyme is a protein that acts as DNA 'scissors', cutting DNA at specific sequences.

Front

What does cloning create?

Back

Cloning creates a gene or organism with the identical genetic material as the original.

Front

Why are restriction enzymes used?

Back

Restriction enzymes are used when the whole chromosome is too large to study easily.

Front

What is gel electrophoresis?

Back

Gel electrophoresis is a technique used to separate DNA fragments based on their size.

Front

What is the role of ligase in biotechnology?

Back

Ligase is an enzyme that joins DNA fragments together, essential in DNA replication and repair.

Front

What is the purpose of DNA amplification?

Back

DNA amplification is used to produce millions or billions of copies of a specific DNA fragment for analysis.

Front

What is a plasmid?

Back

A plasmid is a small, circular piece of DNA that can replicate independently of chromosomal DNA, often used in genetic engineering.

Front

What is gene splicing?

Back

Gene splicing is the process of cutting and recombining DNA to create new genetic combinations.
