Imagine you extract DNA from you and your (nonrelated) friend. If you subjected both DNA samples to restriction digestion using the ApaI restriction endonuclease, do you think the results would be the same or different? Why?
The obtained results by the restriction digestion are different because individual have different genomic content or Allelic contents.
due to the different allelic content and genomic content the restriction sequences and their positions occurs at varying location. The band pattern of restriction digested fragments obtained by digestion shows diversities in their sizes.
Restriction enzymes cuts DNA at their specific site and these specific sites are present at different locations according to individuals.
every human have different location of restriction sites that is why they produce different DNA fragments buy restriction digestion.
