AP Bio Unit 6 Review: Electrophoresis Quiz

What is electrophoresis?

• A type of exercise for the heart

• A technique used to separate DNA, RNA, or proteins based on their size and charge.

• A method for growing plants using electricity

• A process for converting solar energy into electricity

Explain the process of gel electrophoresis.

• Gel electrophoresis separates molecules based on size and charge.

• Gel electrophoresis separates molecules based on color and texture.

• Gel electrophoresis separates molecules based on taste and smell.

• Gel electrophoresis separates molecules based on temperature and density.

What is the purpose of electrophoresis in molecular biology?

• To amplify DNA sequences

• To separate and analyze DNA, RNA, or proteins based on their size and charge.

• To visualize the structure of DNA

• To measure the concentration of DNA in a sample

What are the different types of electrophoresis techniques?

• Chromatography electrophoresis, Spectroscopy electrophoresis, Titration electrophoresis

• Agarose gel electrophoresis, polyacrylamide gel electrophoresis, capillary electrophoresis, and pulsed-field gel electrophoresis

• Western blot electrophoresis, ELISA electrophoresis, PCR electrophoresis

• Centrifugation electrophoresis, Filtration electrophoresis, Distillation electrophoresis

How does electrophoresis separate DNA fragments?

• By taste and smell

• By size and charge

• By temperature and pressure

• By color and texture

What is the role of the gel in gel electrophoresis?

• To provide color to the DNA fragments

• To prevent the separation of DNA fragments

• To act as a medium for separating DNA fragments based on size.

• To speed up the movement of DNA fragments

What are the factors that affect the rate of migration of DNA fragments in electrophoresis?

• Color of the DNA fragments, temperature of the lab, type of pipette used

• Age of the scientist, time of day, brand of the gel box

• Size of DNA fragments, strength of electric field, composition of gel matrix

• Number of students in the lab, humidity in the room, type of gloves worn

What are the applications of electrophoresis in biology?

• Photosynthesis, respiration, and mitosis

• DNA sequencing, DNA fingerprinting, and protein analysis

• Cell division, gene editing, and photosynthesis

• Enzyme activity, cell membrane structure, and cell respiration

What are the limitations of electrophoresis?

• Limited resolution for large DNA fragments, difficulty in separating similar-sized fragments, and the need for specialized equipment and expertise.

• No need for specialized equipment and expertise

• Easy separation of similar-sized fragments

• Unlimited resolution for large DNA fragments

Explain the significance of electrophoresis in genetic research.

• Electrophoresis is used to cook genetic material before analysis

• Electrophoresis helps in mixing genetic material to create new combinations

• Electrophoresis is only used for separating DNA from RNA

• Electrophoresis helps in separating DNA, RNA, or proteins based on their size and charge, allowing for analysis and comparison of genetic material.
