Cosmid vectors are crucial in genetic engineering for cloning large DNA fragments, often between 35 to 45 kilobase pairs. They combine plasmid and bacteriophage lambda DNA, enabling the construction of genomic libraries and the advancement of gene therapy. Despite challenges in handling, cosmids are key to studying gene function and creating genetically modified organisms.
