Difference between Test Plan and Test Strategy. To find out the âDifference between Test Strategy and Test Planâ, first we need to see their individual definition. Test strategy is a high level document which defines the approach for software testing. It is basically derived from the Business Requirement document.
Main Difference: The main difference between nuclear DNA and mitochondrial DNA is, nuclear DNA is the standard 46 chromosome containing DNA in which you inherit 23 chromosome from one parent and the rest 23 from another one.On the other hand, mitochondrial DNA contains just one chromosome, like a circular genome.uclear DNA: Unlike mitochondrial DNA, nuclear DNA is found in every cell of the body. It consists of 46 chromosomes which are inherited from mother and father, both. The are comparatively longer with centromeres and telomers.
Mitochondria carry their own separate DNA (mtDNA) that is independent of the nuclear DNA of the same cell. Human mtDNA is composed of 37 genes totaling about 16,000 base pairs. This mtDNA also mutates at a much faster rate than nuclear DNA (nucDNA) does.ince there were no DNA changes due to genetic recombination events (ie: with paternal DNA-now known to be a wrong assumption), they assumed that all changes in the mtDNA were the result of mutations over time and that these mutations occurred at a constant rate.
