Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Kwayoyin halitta sune manyan raka'a na gado a cikin dukkan kwayoyin halitta. Kwayar halitta ita ce raka'a na gado kuma ya dace da wani yanki na DNA wanda ke rinjayar siffar ko aiki na kwayoyin halitta a wasu hanyoyi. Dukan kwayoyin halitta, daga ƙwayoyin cuta zuwa dabbobi, suna da tsari iri ɗaya wanda yake kwafa da fassara DNA zuwa furotin. Kwayoyin suna rubuta kwayar halittar DNA zuwa wani nau'in RNA na kwayar halittar, kuma ribosome sai ya fassara RNA zuwa jerin amino acid da aka sani da furotin. Lambar fassara daga RNA codon zuwa amino acid iri ɗaya ce ga yawancin halittu. Alal misali, jerin DNA wanda ke tsara insulin a cikin mutane kuma yana tsara insulin lokacin da aka saka shi a cikin wasu kwayoyin halitta, kamar tsire-tsire. DNA an samo shi a matsayin ƙwayoyin chromosomes a cikin eukaryotes, da kuma ƙwayoyin chromosomes a cikin prokaryotes. Chromosome wani tsari ne wanda ya kunshi DNA da histones. Ƙungiyar chromosomes a cikin tantanin halitta da duk wani bayani na gado da aka samo a cikin mitochondria, chloroplasts, ko wasu wurare an san su a matsayin kwayoyin halitta na tantanin halitta. A cikin eukaryotes, DNA na kwayoyin halitta yana cikin kwayar halitta, ko kuma tare da ƙananan ƙwayoyin mitochondria da chloroplasts. A cikin prokaryotes, DNA tana cikin wani jiki mai siffar ba daidai ba a cikin cytoplasm da ake kira nucleoid. Bayanan kwayoyin halitta a cikin kwayoyin halitta ana gudanar da shi a cikin kwayoyin halitta, kuma cikakken taro na wannan bayanin a cikin kwayoyin halitta ana kiransa genotype.  Tambaya: Dabbobi nawa ne suke da kwayoyin halitta?
