You can deduce that a gene lacks introns using nucleic acid hybridization using a eukaryotic gene's dna as the targeting and mrna as the probe.
Large macromolecules called nucleic acids are necessary for all organisms and viruses to function. The preservation and expression of genetic data is a key role of nucleic acids. The information cells require to build proteins is encoded in deoxyribonucleic acid, or DNA.
All cells contain it, as do some viruses. Nucleic acids perform a wide range of tasks, including cell development, the processing and storage of genetic information, the synthesis of proteins, and the production of energy cells.
