Nucleic Acid Hybridization Quiz

What is the primary purpose of nucleic acid hybridization?

• To create new DNA sequences

• To detect specific nucleic acid sequences

• To destroy unwanted DNA

• To replicate DNA in a test tube

During the denaturation process, what happens to the DNA molecules?

• They form RNA molecules

• They become single-stranded

• They are destroyed

• They become double-stranded

What is the purpose of incubation in nucleic acid hybridization?

• To create new DNA sequences

• To destroy the DNA

• To cool down the DNA

• To convert single-stranded DNA back to double-stranded form

What is unique about the DNA probe used in nucleic acid hybridization?

• It is radioactive

• It is invisible

• It is fluorescent

• It is made of RNA

How does a radioactive probe help in detecting specific DNA sequences?

• By destroying non-complementary sequences

• By binding to complementary sequences

• By converting DNA to RNA

• By making DNA invisible

What is the main advantage of using FISH over traditional hybridization techniques?

• It is faster

• It can be used in intact cells or chromosomes

• It is cheaper

• It does not require a microscope

In FISH, what is used to label the DNA probe?

• A magnetic particle

• A chemical reagent

• A radioactive isotope

• A fluorescent dye

What is the role of a fluorescent dye in FISH?

• To destroy DNA

• To replicate DNA

• To make the probe visible under a microscope

• To convert DNA to RNA

What type of microscope is used to observe FISH results?

• Scanning microscope

• Light microscope

• Fluorescence microscope

• Electron microscope

What does the color of the probe in FISH indicate?

• The size of the DNA sequence

• The type of cell

• The specific DNA sequence being targeted

• The temperature of the experiment
