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.
