how do mutations in the DNA sequence affect this type of res

Solution

A restriction enzyme or restriction endonuclease is an enzyme that cuts DNA at or near specific recognition nucleotides sequences known as restriction sites. These enzymes are routinely used for DNA modification in Laboratories and or a vital tool in molecular cloning. Restriction enzymes are used to digest genomic DNA gene analysis by southern blot this technique allows researchers to identify how many copies of a gene are present in the genome of one individual or how many gene mutations have occured within a population. Restriction enzyme digestion has played and continuous to play a major role in analysing the genetic changes in Cancer the availability of 200 different restriction enzymes is recognising different sequences in DNA has been invaluable in studying cancer genetics.Due to mutations in the DNA sequence the chances of these studies are minimised definitely.
