10603.	Question : The genomic content of the nucleus is constant for a given species where as the extrachromosomal DNA is found to be variable among the members of a population. Explain.
Answer» Solution :Many bacteria have small circular DNA outside the genomic DNA. These smaller DNAs are called plasmids. The plasmid DNA confers certain unique phenotype CHARACTERS to such bacteria. e.g. resistance to antibiotics, it is divided IRREGULARLY. So diversity can be found in distribution and number of NEWLY produced living organisms. Active organelles can have its more proportion while inactive organelles can have its less proportion. While DIVISION and distribution of genomic DNA OCCURS in definite way.
