U3 AOS1: Gel Electrophoresis

Front

What is the purpose of gel electrophoresis?

Back

Gel electrophoresis is used for separating DNA fragments by size.

Front

What are DNA samples used for in gel electrophoresis?

Back

DNA samples are the material being analyzed and separated in gel electrophoresis.

Front

What are wells in gel electrophoresis?

Back

Wells are the small indentations in the gel where DNA samples are loaded.

Front

What is a standard ladder in gel electrophoresis?

Back

A standard ladder is a set of known DNA fragments used as a reference to determine the size of DNA fragments in samples.

Front

What is agarose gel?

Back

Agarose gel is a porous matrix used to separate DNA fragments during electrophoresis.

Front

What is the role of buffer solution in gel electrophoresis?

Back

Buffer solution conducts electricity and maintains pH during electrophoresis.

Front

What is the function of electric current in gel electrophoresis?

Back

Electric current moves DNA fragments through the gel.

Front

Why is DNA attracted to the positive electrode in gel electrophoresis?

Back

DNA is negatively charged, so it moves towards the positive electrode.

Front

What are pores in the context of gel electrophoresis?

Back

Pores are the small spaces in the agarose gel that allow DNA fragments to move through.

Front

What are bands in gel electrophoresis?

Back

Bands are the visible lines of DNA fragments separated by size in the gel.
