Structure X includes a deoxyribose sugar, a phosphate group, and a nitrogenous base. What is this structure called?

Answer 1

Structure X, which consists of a deoxyribose sugar, a phosphate group, and a nitrogenous base, is called a nucleotide. In the context of DNA, it is specifically referred to as a deoxyribonucleotide. Nucleotides are the basic building blocks of nucleic acids such as DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). The nitrogenous base in a deoxyribonucleotide can be one of four types: adenine (A), cytosine (C), guanine (G), or thymine (T). In RNA, the sugar would be ribose rather than deoxyribose, and the base would be uracil (U) instead of thymine.
