DNA profiling techniques of blood require DNA sample and we know that DNA is present in the nucleus of cells.
Option A is incorrect as serum is the light yellow liquid left after blood clotting and does not contain any blood cells.
Option B is incorrect as erythrocytes are enucleated cells and hence lack DNA.
Option D is incorrect as significantly platelets are small fragments of megakaryocytes and do not have the nucleus.
Option C is correct as leucocytes are large cells with nucleus which in turn house DNA that can be used as the sample for DNA profiling of the blood stains.

Restriction endonuclease was isolated for the first time by W. Aber in 1962 in bacteria. Restriction endonucleases cut the DNA duplex at specific points therefore they are also called as molecular scissors or biological scissors. Three types of restriction endemicleases are Type 1. Type 11 and Type III but only Type II restriction endonucleases are used in recombinant DNA technology. Restriction endonuclease EcoR I recognises the base sequence GAATTC In DNA duplex and cut strands between G and A.
Which type of restriction endonucleases is used most in genetic engineering?
(A) Type I
(B) Type II
(C) Type III
(D) Type IV
