31. Certain restriction enzymes recognize the same sites, and cannot contribute productively to the analysis. 32. Fisher also used a restriction enzyme accessibility assay to observe nucleosome transformation upon macrophage stimulation. 33. That letter stimulated me to think of using restriction enzymes to analyze the genes of SV40, 34. This would help digest sequences that are not being recognized by methylation-sensitive restriction enzymes . 35. After studying slow lorises from Indochina, polymorphic loci, and mitochondrial DNA restriction enzyme analysis. 36. Further complications could arise when incomplete digestion of DNA by restriction enzymes generated false negative results. 37. This page does have a decent, but basic description of how a restriction enzyme works. 38. The specific restriction enzyme cleaves the genomic DNA at random points, and generates recognition sites. 39. Other viruses, such as bacteriophages T3 and T7, encode proteins that inhibit the restriction enzymes . 40. Each restriction enzyme cuts DNA at a specific nucleotide sequence, resulting in fragments of different lengths.
