Deoxyribonucleic Acid

Polymerase Chain Reaction

Fill in the Blanks

A drawback to using restriction fragment length polymorphism (RFLP) is that you need a

sample.

Draw

A restriction enzyme uses the sequence "TCGTAG". Draw a vertical line showing where this strand of DNA would be cut in two.

Draw

A restriction enzyme uses the sequence "GGATCA" for the top strand and "AGTCGGCG" for the bottom strand. Draw a line where this cut will be made.

Multiple Choice

What is used to "cut" DNA for processing for analysis like restriction fragment length polymorphism or gel electorophoresis?

Promoter Regions

Restriction enzymes

Splicing restriction polynucleases

Nucleic polymer fragment generators

Categorize

Options (4)

Determine if the following DNA samples of blunt ends or sticky ends.

Blunt Ends

Sticky Ends

Multiple Choice

What does the polymerase chain reaction (PCR) do?

Cuts DNA into pieces

Separates DNA fragments by size

Makes copies of DNA fragments for more accurate and reliable testing.

Processes DNA fragments into proteins.

Reorder

Put the steps of PCR in order.

Denaturing

Annealing

Extension

Multiple Choice

Why use PCR for DNA analysis instead of RFLP?

PCR is preferred for its speed and sensitivity in amplifying DNA.

RFLP is faster and easier to perform than PCR.

RFLP provides more detailed information about DNA sequences than PCR.

PCR requires more DNA than RFLP for analysis.
