Retrovirus - Wikipedia
网页A retrovirus is a type of virus that inserts a DNA copy of its RNA genome into the DNA of a host cell that it invades, thus changing the genome of that cell. [ 2 ] . After invading a host cell's cytoplasm, the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backward).

网页逆转录病毒科 （学名： Retroviridae）又稱「反轉錄病毒科」，分爲 雙鏈 DNA逆轉錄病毒 和 正鏈RNA逆轉錄病毒。 它们增殖時都有將遺傳物質RNA逆轉錄爲DNA的過程（前者逆轉錄反鏈RNA，後者逆轉錄正鏈RNA），多具有 逆转录酶。 本文主要介紹 正鏈RNA逆轉錄病毒。 逆轉錄病毒. 於1908年於 丹麥 証明、1911年於 美國 進行人工實驗証實此病毒科之存在。 逆轉錄病毒大小約為100nm（70~110nm，有時至200nm），外面為一層具有表面突起的 …
反转录病毒 - 百度百科
网页逆转录病毒（Retrovirus），又称反转录 病毒，属于RNA病毒中的一类，它们的遗传信息不是储存在 脱氧核糖核酸 （DNA），而是储存在 核糖核酸 （RNA）上。 逆转录病毒基因组为二倍体，两条相同的单股正链RNA，其两端为长末端重复序列（LTR），内含有较强启动子和增强子，对病毒DNA的转录调控具有重要作用。 病毒核心包含 逆转录酶 和整合酶。 与其他RNA病毒不同之处在于，逆转录病毒的RNA不进行自我复制，进入宿主细胞后，RNA经 …
