Background:

• Advancements in multicomponent molecular biological tools necessitate efficient DNA plasmid assembly.
• Existing cloning platforms often lack affordability, ease of combinatorial assembly, and modularity.
• The ability to iteratively remove DNA cassettes is crucial for complex molecular biology workflows.

Purpose of the Study:

• To develop a versatile, rapid, and cost-effective cloning system for combinatorial DNA plasmid assembly.
• To create a molecular cloning platform that allows simultaneous expression of multiple constructs.
• To introduce a novel feature enabling the selective removal of individual DNA cassettes at any stage.

Main Methods:

• Construction and implementation of a novel set of cloning vectors, termed PlayBack vectors.
• Utilizing separate promoters for simultaneous expression of diverse DNA constructs.
• Demonstrating the selective removal of individual DNA cassettes within the cloning platform.

Main Results:

• The PlayBack vector system offers a substantially cheaper alternative to existing multicomponent cloning systems.
• The system demonstrates broad usability across a wide range of experimental paradigms.
• A key feature is the novel ability to selectively remove components of interest at will.

Conclusions:

• The PlayBack vectors provide a cost-effective and versatile solution for complex DNA plasmid assembly.
• This molecular cloning platform enhances experimental flexibility through simultaneous expression and selective cassette removal.
• The developed system addresses limitations of current cloning strategies, offering significant advantages for researchers.
