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.

What is one way that a lysogenic infection differs from a lytic infection?

• A lysogenic virus does not act on bacteria as a lytic virus does.
• A lysogenic virus can remain in the host DNA for a longer period without becoming active.
• A lysogenic virus contains RNA instead of DNA.
• A lysogenic virus directs the production of new viruses right away.

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation
