I-molecule ye-DNA ethwala i-chromosome ibizwa ngokuthi i-DNA
Impendulo ithi: isakhi sofuzo.
Amangqamuzana e-DNA athwalwa ku-chromosome ayingxenye ebalulekile yezakhi zofuzo.
I-DNA inokwaziswa okudingekayo ukuze kwenziwe amaprotheni, izinto zokwakha ukuphila.
Wonke amangqamuzana asemzimbeni womuntu anama-chromosome, akhiwe ama-molecule e-DNA.
Ingqamuzana ngalinye le-DNA liphethe izakhi zofuzo ezineziqondiso zokwenza amaprotheni.
Izakhi zofuzo zisuka kubazali ziye ezinganeni zabo, okusivumela ukuba sizuze njengefa izici zethu ezingokomzimba.
Isakhi sofuzo esinesici singaholela ezifweni nasezimeni ezihlukahlukene.
Ngokutadisha ukwakheka nemisebenzi ye-DNA, ososayensi baye bakwazi ukuqonda kangcono izifo zofuzo, bathuthukise izindlela zokwelapha, futhi bahlonze amakhambi angenzeka.
Ukuqonda indima ye-DNA ku-chromosome kungasisiza senze izinqumo ezinolwazi mayelana nempilo yethu nokuphila kahle.
