Distinguish between Plasmid DNA and chromosomal DNA

अंतर स्पष्ट करें

उत्तर

Sr. no. Plasmid DNA Chromosomal DNA
1. Plasmids are circular external DNA that is self-replicating and are naturally found in bacteria and yeast. Chromosomal DNA sequence, including recognition site, is present in the chromosomes of all organisms.
2. It is not necessary for normal growth and division. This is necessary for growth and division.
3. It contains information about some properties of the cell. It contains information about all the properties.
