What is your problem what subject
Answer:
B. The ddNTPs lack a 3′ hydroxyl group.
Explanation:
Dideoxynucleotides is a family of inhibitors of the DNA polymerase, its official name is 2',3' dideoxynucleotides but they are commonly called ddNTPs. One of the main characteristics of this compound is the absence of the 3'-hydroxyl group in the deoxyribose, due to the absence of this group, it is impossible to form a phosphodiester bond between nucleotides and the DNA synthesis is stopped.
Amylase and other carbohydrase enzymes break down starch into sugar. protease enzymes break down proteins into amino acids. lipase enzymes break down lipids (fats and oils) into fatty acids and glycerol.
