Restriction enzymes are essential tools in molecular biology because each recognizes a unique DNA sequence and precisely cuts the double-stranded DNA molecule into smaller, distinct fragments. Taq I is a Restriction Endonuclease purified from an Thermus aquaticus strain that carries the Taq I gene. The restriction enzyme Taq I recognizes the DNA sequence T^C G A and optimally cleaves the DNA at 37°C when used with 10X Assay Buffer. Taq I is a Thermostable Endonuclease isolated from Thermus aquaticus that remains active at high incubation temperatures. This Restriction Enzyme targets the TCGA Recognition Sequence for use in Restriction Fragment Polymorphism Analysis and genomic studies.
