Questions & Step-by-Step Solutions
What is the role of a selectable marker in a vector?
Step 1: Understand what a vector is. A vector is a tool used in genetic engineering to carry DNA into a cell.
Step 2: Learn about selectable markers. These are genes included in the vector that help identify which cells have taken up the vector.
Step 3: Know how selectable markers work. They usually provide a way for cells to survive in certain conditions or to show a visible change.
Step 4: Realize the importance of selectable markers. They allow scientists to easily find and select the cells that have successfully incorporated the vector.
