WebFosmid. Fosmids are similar to cosmids but are based on the bacterial F-plasmid. The cloning vector is limited, as a host (usually E. coli) can only contain one fosmid molecule. Fosmids can hold DNA inserts of up to 40 kb in size; often the source of the insert is random genomic DNA. A fosmid library is prepared by extracting the genomic DNA ... WebCosmid vectors are prepared by inserting the cos sequence of a phage into a small plasmid vector, since the cos sites enable the DNA to get packed in lambda particle, cosmids allow the packaging of DNA in phage particle in …
