Why did scientists edit the genes of bacteria to produce insulin?

• Because the bacteria were diabetic

• Because bacteria have simple DNA that is easier to manipulate, making it easy to produce insulin in a lab

• Because bacteria's complex DNA was perfect for insulin production

• Because insulin has no use outside of a lab setting

Which agricultural benefit can biotechnology  provide?

• developing plants that are less dependent on the sun for energy
• developing plants that are less sensitive to variations in environmental temperatures
• developing plants with inheritable traits unrelated to the genetic material they contain
• developing plants that will not die

Examine the results for group 4. Why would this group see growth without RFP in the third plate?

• The bacteria cells did not transform.

• The bacteria cells transformed, but did not incorporate the plasmid containing the RFP gene.

• The bacteria cells transformed, but did not incorporate the plasmid with the arabinose gene.

• Group 4 did not observe growth in the third plate.

What is the relationship between proteins and traits?

• Proteins carry the genetic information that is responsible for traits.

• Traits control protein expression.

• Proteins produced by expression of genes result in traits

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 gene therapy?

• Inserting copies of a healthy gene directly into cells with a mutated gene
