Gel Electrophoresis

This laboratory procedure is known as

• CLONING

• gel electrophoresis

• chromatography

• use of a dichotomous key

In preparation for an electrophoresis procedure, enzymes are added to DNA in order to

• convert the DNA into gel

• cut the DNA into fragments

• change the color of the DNA

• produce longer sections of DNA

Which chemicals are used to cut DNA into fragments for a gel electrophoresis procedure?

• enzymes

• molecular bases

• hormones

• ATP molecules

This technique used to analyze DNA involves the

• synthesis of new DNA strands from subunits

• separation of DNA fragments based on size

• production of genetically engineered DNA molecules

• removal of defective genes from DNA

Based on these results whose blood was found in the blood stain at the crime scene?

• Bob
• Sue
• John
• Lisa

Which two bear species are most closely related?

• Bear 1 and Bear 2
• Bear 1 and Bear 3
• Bear 2 and Bear 3
• There’s no way to tell

Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode?

• DNA is negatively charged so attracted to the positive end of the unit
• DNA is positively charged to attracted to the negative end of the unit
• the agarose gel in negatively charged
• the agarose gel is positively charged

What is the purpose of gel electrophoresis?

• helps cut DNA
• count the genes in DNA
• separates DNA based on size
• allows for an exact replicated organism
