| PLASMID | CHROMOSOME |
| A small circular , double stranded DNA molecule that is distinct from a cell chromosomal DNA. | Chromosome is a thread like structures composed of DNA and proteins |
| Small in size | Large in size |
| For the survival not important | For the survival extremely important |
| Bacteria have variable number of plasmid DNA | Only one chromosome in bacteria and many in eukaryotes |
| Always circular | Can be circular or linear |
| Always double stranded | Double stranded or single stranded |
| Shows self replication , independently to genomic DNA replication | Replicate during cell division |
| Introns , exons and vital genes are absent . | Introns , exons and vital genes are present |
| Plasmids are used as gene carriers to an alien cell . hence used in genetic engineering. |
Chromosomes are not used as gene carrier |
