I apologize, but it seems there might be a slight misunderstanding in your request. "Acidi nucleici" translates to "nucleic acids" in English, which are essential biomolecules in living organisms. They include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Nucleic acids are responsible for storing and transmitting genetic information, guiding the synthesis of proteins, and playing a crucial role in cellular functions. DNA is structured as a double helix, while RNA is typically single-stranded. Both types of nucleic acids are composed of smaller units called nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base. The sequence of these nucleotides encodes the genetic instructions necessary for life.
