Question

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? a lipids are responsible for carrying the genetic material and carbohydrates are responsible for catalyzing the reaction. b carbohydrates are responsible for carrying the genetic material and nucleic acids are responsible for catalyzing the reaction. c proteins are responsible for carrying the genetic material and lipids are responsible for catalyzing the reaction. d nucleic acids are responsible for carrying genetic material and proteins are responsible for catalyzing the reaction.

Explanation:

To solve this, we analyze biomolecule functions:

• Nucleic acids (like DNA/RNA) carry genetic material.
• Proteins (enzymes) act as catalysts (speed up reactions).

Now evaluate options:

• Option A: Lipids don't carry genetic material, carbs don't catalyze. Eliminate.
• Option B: Carbs don't carry genetic material, nucleic acids don't catalyze (enzymes do). Eliminate.
• Option C: Proteins don't carry genetic material, lipids don't catalyze. Eliminate.
• Option D: Matches nucleic acids (carry genetic material) and proteins (catalyze reactions) functions.

Answer:

D. Nucleic acids are responsible for carrying genetic material and proteins are responsible for catalyzing the reaction.
