perimäainesta
Perimäainesta, literally meaning hereditary material, is the substance that carries the information responsible for inheritance in biological organisms. In the vast majority of life, this material is deoxyribonucleic acid (DNA), which stores genetic instructions in sequences of nucleotides. Some viruses use ribonucleic acid (RNA) as their genome, in which case RNA serves as the genetic material. Perimäainesta contains genes and regulatory regions that control how traits are expressed, developed, and maintained.
