The correct answer is bâcatalyzing a series of reactions using multiple different enzymes B. Answer b is correct. The enzymes within a multienzyme complex all work on complementary reactions in which the product of one reaction supplies the substrate for the next. The correct answer is bâ C. Answer c is incorrect. Enzymes catalyze reactions by lowering the activation energy; however, this property is not unique to multienzyme complexes. The correct answer is bâ D. Answer d is incorrect. Multienzyme complexes contain more than a single enzyme and although they do lower the activation energy, that property is not unique to these complexes.
A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.More than 400 restriction enzymes have been isolated from the bacteria that manufacture them. The number of cuts in an organism's DNA made by a particular restriction enzyme is determined by the number of restriction sites specific to that enzyme in that organism's DNA. 2  A fragment of DNA produced by a pair of adjacent cuts is called a RESTRICTION FRAGMENT.
