 The basic principle of the PCR reaction is to heat the DNA to be copied to >90ºC to denature it
the strains can be differentiated from each other and from BL21(DE3) by transformation with a strain verification vector

DNA Fingerprinting size:For 6 groups of 4-5 or 24-30 students. Â Small moleculesTodays media routinely covers forensic stories of criminals captured and innocents released using the powerful DNA fingerprinting technique. This kit allows students to carry out their own criminal investigation by comparing DNA samples collected from suspects to DNA collected at a pseudo crime scene. Students will use specialized molecules to cut the DNA into fragments, which can then be visualized by a process known as electrophoresis. The resulting
