Identify a sequence as plasmid
Hello
I have a 61 kb sequence generated during the sequencing of whole genome of a bacteria. The main chromosome is 6.2Mb and have all the essential copy genes whereas the 61 Kb sequence does not have any chromosomal genes. What should I do to show that this sequence is of the plasmid.

Does whole genome sequencing capture plasmids?
written by robjohn70000
do you expect the plasmid to be present in multiple copies? if so, also the sequencing coverage should be higher. this could be an indication of an actual plasmid.
A plasmid will be circular, so you would have reads that contain both end sequences (3' followed by 5'). Higher than average copy number is another clue, but repeat elements (e.g., multiple insertions of a transposon or prophage) will also share this characteristic.
