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.
Answer:
The answer is a Carbohydrate!
A disaccharide (also called a double sugar or biose[1]) is the sugar formed when two monosaccharides (simple sugars) are joined. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose,[2] and maltose.
Disaccharides are formed by the condensation reactions of two simple sugar molecules.
