Comparison of Four-, Six-, And Eight-bp Cuts in Calf Thymus Dna
Pupils investigate the use of restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. They utilize restrictive endonucleases to cut Thymus DNA and compare results by viewing the DNA fragments on Agarose Gel Electrophoresis.
