Directions: Complete the paragraph below by supplying the missing information

_(1)_ cut DNA molecules at specific locations called restriction SAS. In nature, bacteria use restriction enzymes to cut foreign DNA and protect their own DNA by methylation. Restrictions enzymes recognize short DNA nucleotide $equences and cut at specific point in these sequences. Because the target sequence usually occurs many times on a long DNA molecule, an enzyme will make any cuts. Copies of a DNA molecule will always yield the same set of _(2)_ fragments when exposed to a specific enzyme. Restriction enzymes leave _(3)_ These will bond with complementary single- stranded stretches on other DNA molecules cut with the same restriction enzyme._(4)_ seals the strand. Thus, creating the _(5)_DNA.
