31. Care should be taken to choose the restriction enzymes . 32. Arber had discovered the type of restriction enzymes that dismantle genetic material at specific points. 33. This page does have a decent, but basic description of how a restriction enzyme works. 34. PCR products are then treated with a restriction enzyme ( " e . g ." 35. Restriction endonucleases or restriction enzymes typically cleave in two ways : blunt-ended or sticky-ended patterns. 36. Fisher also used a restriction enzyme accessibility assay to observe nucleosome transformation upon macrophage stimulation. 37. The specific restriction enzyme cleaves the genomic DNA at random points, and generates recognition sites. 38. The nucleotide sequence recognized for cleavage by a restriction enzyme is called the restriction site. 39. That letter stimulated me to think of using restriction enzymes to analyze the genes of SV40, 40. Each restriction enzyme cuts DNA at a specific nucleotide sequence, resulting in fragments of different lengths.
