Questions & Step-by-Step Solutions
Which of the following vectors can carry the largest DNA inserts?
Step 1: Understand what a vector is. A vector is a tool used to carry and transfer DNA into a host cell.
Step 2: Learn about different types of vectors: plasmids, viral vectors, cosmids, and bacterial artificial chromosomes (BACs).
Step 3: Know that plasmids are small and can carry only a small amount of DNA.
Step 4: Understand that viral vectors can carry moderate amounts of DNA but are limited in size.
Step 5: Learn that cosmids can carry larger DNA inserts than plasmids and viral vectors, but still have size limitations.
Step 6: Discover that bacterial artificial chromosomes (BACs) are designed to carry very large DNA inserts, much larger than the other types of vectors.
Step 7: Conclude that BACs can carry the largest DNA inserts compared to plasmids, viral vectors, and cosmids.
