✔ 最佳答案
成熟的紅血球沒有DNA，因沒有細胞核，而DNA等遺傳物質儲於細胞核內。
依本人所見，紅血球並非原核細胞，
因為紅血細胞是特化細胞，
形成過程中是有細胞核的。
而人亦非原核生物。
依個人所見，原核細胞主要係單細胞生物的唯一細胞，
人體的細胞則屬真核細胞

可以話有又可以話冇年輕既紅血球就有細胞核，所以有dna。而成熟既紅血球則無細胞核，因為要節省位置放更多氧，所以冇dna。人體成熟既紅血球較多。

紅血球冇DNA!
Red blood cell had DNA when it was an immature cell. Normal red blood cell that is circulating in the body does not contain nucleus. Therefore, it has no DNA. It is the only cell in the body that does not contain DNA!
