Caryoplastin is a term commonly used in biology and medicine, referring to a substance that can dissolve cell nuclei. Its spelling can be explained using IPA phonetic transcription as /ˌkærɪəˈplæstɪn/, with the emphasis on the second syllable. The pronunciation of the word caryoplastin is similar to "carry-o-plastin" or "care-ee-o-plastin". The word derives from the Greek words "karyon", meaning "nucleus", and "plastos", meaning "formed" or "molded". In essence, caryoplastin is a substance that molds itself to dissolve cell nuclei, making it an important tool for cellular studies.
