Nukleotilla

Nukleotilla is not a standard term in biochemistry. In real science, the correct word is nucleotide (plural nucleotides). The form "nukleotilla" may appear as a transliteration, localization variant, or misspelling in non-English sources, and it can lead to nonstandard usage outside formal literature.

A nucleotide is the basic building block of nucleic acids. It consists of a five‑carbon sugar (deoxyribose in DNA or ribose in RNA), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine in DNA; adenine, cytosine, guanine, or uracil in RNA). Nucleotides link through phosphodiester bonds between the sugar of one unit and the phosphate of the next, forming the sugar–phosphate backbone of DNA or RNA. The sequence of bases encodes genetic information, while certain nucleotides function as energy carriers (ATP), cofactors (NAD+, FAD), or signaling molecules (cAMP, cGMP).

In fictional or educational contexts, "nukleotilla" may be used to describe a hypothetical or simplified unit analogous to a nucleotide, or as a pedagogical variant for teaching basic molecular biology. Such usage is nonstandard and should be distinguished from real biochemistry.
