Review for Biotechnology Test

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

The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel

electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?

• They have the correct child, because her genetic information is identical to that of the father.

  
  

• They have the wrong child, because her genetic information does not match that of either parent.

• They have the correct child, because her genetic information came from both parents.

  
  

• They have the wrong child, because her genetic information matches only that of the mother.

A student performed a gel electrophoresis experiment. The results are represented in the diagram

below. Compared to the fragments at the top of the gel, the fragments at the lower end are

• larger, and move slower

• larger, and move faster

• smaller, and move faster

• smaller, and move slower

What is recombinant DNA

• DNA from 2 different organisms combined

• DNA from 2 different ribosomes

• DNA that is separated out from a vector
