WebA restriction enzyme is produced within the bacterial cell due to which it is also called “Restriction endonuclease”. In 1978, Werner Arber, Daniel Nathans, Hamilton O Smith … WebAnswer (1 of 3): In bacteria the restriction enzymes (RE) play a protective role by destroying the foreign DNA, like that from the viruses. The viral DNA is non-methylated so that RE can differentiate between self DNA (which is methylated), from the foreign (which is non-methylated). This is a ki...
WebA restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence . More than 400 restriction … WebIn general, restriction enzymes cleave double-stranded DNA. Each restriction enzyme recognizes specific DNA sequences, and cleavage can occur within the recognition sequence or some distance away, depending on the enzyme. The recognition sequences are generally 4 to 8 base pairs (bp) in length, and cleavage can produce sticky ends (5′ …
