Assertion: When the DNA sequences of two
people are cut using the same restriction enzyme,
the length and number of fragments obtained
are different for both.
Reason: DNA sequence is arranged tandemly
in many copy numbers which varies from
chromosome to chromosome in an individual,
showing high degree of polymorphism.
