Why is it essential to have a selectable marker in a cloning vector?

Explore the crucial role of selectable markers in cloning vectors, an essential concept for students in Class 12 Tuition. As an experienced tutor registered on UrbanPro.com, let's delve into why selectable markers are indispensable and highlight the platform's commitment to providing the best online coaching for Class 12 Tuition.

Understanding Selectable Markers in Cloning Vectors:

1. Definition of Selectable Marker:

   • A selectable marker is a gene introduced into a cloning vector to identify and select for cells that have successfully taken up the vector.

2. Purpose of Selectable Markers:

   • Selectable markers serve as tools for distinguishing transformed cells from non-transformed ones during the process of gene cloning.

3. Identification of Transformed Cells:

   • Selectable markers enable the identification of cells that have successfully incorporated the cloning vector into their genome.

4. Resistance to Antibiotics:

   • Commonly used selectable markers confer resistance to antibiotics. For example, the introduction of an antibiotic resistance gene into the vector.

5. Survival Advantage for Transformed Cells:

   • Cells that have successfully taken up the vector with a selectable marker gain a survival advantage, as only they can thrive in the presence of the antibiotic.

Significance in Class 12 Tuition:

1. Integral to Gene Cloning Techniques:

   • Understanding the role of selectable markers is fundamental for Class 12 students studying gene cloning techniques in biotechnology.
