Hey dear !!

So here's your answer :-

The genomic content of nucleas is species specific example 23 pairs of choromosomes in all the human beings of the world.

It is related to hereditary information.
Each chromosome has a specific sequence. This specific genomic content is maintained by its duplication in "S-phase" followed by its specific arrangement and separation during "M- phase" of the cell cycle.

Loss of any choromosome cause loss of many gases which is generally fatal.

But, the content of extra - choromatal DNA is not species specific as it doubling and separation is not a random process and may or may not occur.

The genes of extra - genomic DNA are not so vital for the survival of organism.


Hope this helps you dear ✌✌✌

heya.........


The DNA content of the nucleus is constant for a given species. The haploid organisms have half the content of DNA than that of their diploid parents.

The amount of DNA remains constant in all the members of a given species. On the other hand, the extra chomosomal DNA which occur either in the mitochondria or in chloroplast is found to be variable among the members of a population.

 In case of highly active organisms, the DNA (extrachromosomal) is found to be more as compared to less active ones.


hope this will help u--:)
