What is the purpose of PCR in DNA analysis?

Back

To produce millions of copies of a specific region of DNA.

Front

Which biological structure contains DNA organized into pairs?

Back

Chromosomes.

Front

In gel electrophoresis, do smaller DNA fragments travel farther than larger ones?

Back

True.

Front

What is DNA fingerprinting primarily used for?

Back

To identify individuals based on their unique DNA profiles.

Front

What is the role of restriction enzymes in DNA analysis?

Back

To cut DNA at specific sequences, creating fragments for analysis.

Front

What is the significance of the 23 pairs of chromosomes in humans?

Back

They contain the genetic information inherited from both parents.

Front

How does gel electrophoresis separate DNA fragments?

Back

By applying an electric current that causes DNA fragments to move through a gel matrix.

Front

What is the first step in the DNA fingerprinting process?

Back

Collecting DNA samples from the crime scene and suspects.

Front

What does a DNA profile represent?

Back

A unique pattern of DNA markers that can identify an individual.

Front

What is the function of DNA polymerase in PCR?

Back

To synthesize new DNA strands by adding nucleotides to the template strand.
