... Apo-repressor can only bind to the operator site of trp operon when a tryptophan molecule, which is a co-repressor, binds to it. Apo-repressor acts as an inducer if there is a lesser amount of tryptophan present in the surrounding medium and remains inactive when sufficient tryptophan is present. Ap ...

Recombinant DNA and Cloning
... • Isolate and purify all the DNA from a sample of human cells. Break apart the cells and then wash, centrifuge, and use other purification techniques. • • Cut the DNA into millions of small fragments using restriction enzymes. Each DNA piece may be as large as 10 kb, but is more commonly 1 to 5 kb. ...
