Question

Quizplus · Accepted Answer

Deoxyribonucleoside triphosphates (dNTPs) are the raw materials used for DNA synthesis. They consist of a deoxyribose sugar, a nitrogenous base (adenine, thymine, cytosine or guanine) and three phosphate groups. During DNA synthesis, the phosphate groups are cleaved, releasing energy and forming phosphodiester bonds between adjacent nucleotides, resulting in the formation of a DNA strand. The other options listed are not used in the synthesis of DNA, but rather in other cellular processes.
