 <translate> Tsarin kwayar halitta, ko tsarin rarraba kwayar halitta, shine jerin abubuwan da ke faruwa a cikin kwayar halitta wanda ke haifar da rarrabuwa da kwafin DNA (kwafin DNA) don samar da sel biyu na 'ya'ya. A cikin ƙwayoyin cuta, waɗanda ba su da kwayar halitta, zagayen tantanin halitta ya kasu kashi biyu, B, C, da kuma D. Lokacin B ya wuce daga ƙarshen rarraba kwayar halitta zuwa farkon kwafin DNA. Kwafin DNA yana faruwa a lokacin C. Lokacin D yana nufin matakin tsakanin ƙarshen kwafin DNA da rarraba kwayar kwayar cuta zuwa sel biyu na 'ya'ya. A cikin ƙwayoyin da ke da kwayar halitta, kamar yadda yake a cikin eukaryotes, an kuma rarraba tsarin tantanin halitta zuwa lokaci uku: interphase, mitotic (M) lokaci, da kuma cytokinesis. A lokacin interphase, tantanin halitta yana girma, yana tara abubuwan gina jiki da ake buƙata don mitosis, shirya shi don rarraba tantanin halitta da yin kwafin DNA. A lokacin mitotic lokaci, chromosomes raba. A lokacin mataki na ƙarshe, cytokinesis, chromosomes da cytoplasm sun rabu zuwa cikin sabbin sel biyu na 'ya'ya. Don tabbatar da rarrabawar kwayar halitta, akwai tsarin sarrafawa da aka sani da ƙwayoyin cuta.  Amsa wannan tambaya: yaushe ne cytokinesis ke faruwa a cikin kwayar halitta? Bari mu yi tunani da sauri.
