Question: What is the purpose of using marker genes in transgenic plant development?

Options:

  1. To enhance photosynthesis
  2. To identify successfully transformed cells
  3. To increase water retention
  4. To improve soil quality

Correct Answer: To identify successfully transformed cells

Solution: 

Marker genes are used to identify successfully transformed cells, allowing researchers to select plants that have incorporated the desired genetic material.

Questions & Step-by-Step Solutions

What is the purpose of using marker genes in transgenic plant development?
  • Step 1: Understand that transgenic plants are created by adding new genes to their DNA.
  • Step 2: Realize that not all plant cells will successfully take up the new genes.
  • Step 3: Learn that marker genes are special genes that help identify which cells have successfully taken up the new genes.
  • Step 4: Know that these marker genes often provide a visible trait, like resistance to a herbicide or a color change.
  • Step 5: Understand that researchers can then grow the plant cells and select only those that show the marker trait.
  • Step 6: Conclude that this selection process helps ensure that only plants with the desired genetic material are developed.
