Detailed explanation-1: -Plasmids are replicons that are maintained as discrete, extrachromosomal genetic elements in bacteria. They are usually much smaller than the bacterial chromosome, varying from less than 5 to more than several hundred kbp, though plasmids as large as 2 Mbp occur in some bacteria.
Detailed explanation-2: -The plasmid DNA is a circular, double-stranded extrachromosomal DNA, which is relatively smaller in size compared to chromosomal DNA. The presence of plasmid DNA is in prokaryotes only, whereas chromosomal DNA is present both in prokaryotes and eukaryotes.
Detailed explanation-3: -Genomic DNA is found in both prokaryotes as well as eukaryotes. Plasmid DNA is found only in prokaryotes like bacteria, and also in a few eukaryotes. It is a chromosomal DNA larger than the plasmid DNA. It is extrachromosomal DNA that is comparatively smaller.
Detailed explanation-4: -Plasmids are bacterial DNA molecules that are smaller than the chromosome(s). Generally, they are dispensable for bacterial growth at least under some conditions.
Detailed explanation-5: -Abstract. Bacteria genomes are small, ranging from 100 to 15 000 kb in length, but they harbor a vast reservoir of genetic and physiological diversity.
