One way in which genetically modified mice are developed is by injecting the gene sequence for green fluorescent protein (GFP) into a mouse embryo at a very early stage of development. The injection typically contains genetic material and a biomolecule that catalyzes the reaction. Which statement BEST classifies the biomolecules responsible for the development of these genetically modified mice?

  1. Lipids are responsible for carrying the genetic material and carbohydrates are responsible for catalyzing the reaction.
  2. Carbohydrates are responsible for carrying the genetic material and nucleic acids are responsible for catalyzing the reaction.
  3. Proteins are responsible for carrying the genetic material and lipids are responsible for catalyzing the reaction.
  4. Nucleic acids are responsible for carrying genetic material and proteins are responsible for catalyzing the reaction.

1. Understand the question

The injection contains genetic material and a molecule that catalyzes a reaction. Match each job to its biomolecule.
