Cytosine CAS:71-30-7

He mea nui te cytosine ki ngā momo whakamahinga koiora me te matū. I roto i te ira me te koiora ngota, he mea nui kia mārama ki te hanganga me te mahi a ngā waikawa karihi. Mā te kaha o te cytosine ki te hanga hononga hauwai ki te guanine ka taea e ia te whai wāhi ki te hanganga takirua-helix o te DNA me ngā ngota RNA i te wā o ngā tukanga whakawhiti me te whakamāori. Heoi anō, ka pāngia te cytosine e ngā whakarerekētanga matū ka pā ki te whakahaere ira, te epigenetics, me ngā āhua mate, ka waiho hei kaupapa rangahau nui i roto i ngā mara pēnei i te koiora mate pukupuku me te koiora whanaketanga. I roto i te umanga rongoā, ka tūhuratia te cytosine me ōna analogs mō ō rātou pūmanawa i roto i ngā maimoatanga ārai huaketo me te ārai mate pukupuku, e aro ana ki te pākia o te waikawa karihi me te hanga pūmua. Hei tāpiri, i roto i te matū waro, ka whakamahia ngā matū cytosine hei poraka hanga mō te hanga o ngā matū hou me ngā tono pūtaiao rongoā me te rauemi. Ko tōna hiranga i roto i ngā tukanga koiora taketake me ngā mahi pūtaiao tono e whakaatu ana i te hiranga whānui o te cytosine i roto i ngā momo mara ako me te ahumahi.
