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.
Is called autotroph organisms that create organic molecules needed for survival from inorganic sources. this is achieved through photosynthesis (which is light energy) or chemosynthesis (which is chemical energy).
And photosynthesis is when autotrophs capture and convert the light energy from the sun into usable chemical energy (which is their food).
i just answered the same question like 20 min ago XD
