Question

Quizplus · Accepted Answer

Restriction enzymes recognize and cut DNA at specific base sequences, known as restriction sites. This specificity allows for precise manipulation of DNA sequences in genetic engineering and other molecular biology applications. Sticky ends are a result of restriction enzyme cutting and do not limit their function. While restriction enzymes can produce fragments of uniform length, this is not always the case and is dependent on the specific enzyme and DNA sequence being cut. Restriction enzymes are produced by bacteria as a defense mechanism against foreign DNA, not by viruses to break down bacterial DNA.
