第三章 DNA复制、转录和翻译.ppt,第二章 DNA的复制、转录及翻译 Replication, transcription and translation of DNA 1.1 复制子 (replicon) 从每个复制起始点到复制终点的区域,能独立进行复制的单位。 原核生物:单一复制子 真核生物:多个复制子, 1.2 DNA复制的方向和
说到“中心法则”(Central Dogma),想必大家定不会陌生,这一现代生命科学的基本定律由英国著名生物学家 Francis Crick 于 1958 年正式提出。它指明了遗传信息的标准流程,即“DNA→DNA(DNA 的自我复制,replication),DNA→RNA(转录,transcript...
There are three steps in the process of generating a protein from the information stored within DNA: transcription, RNA processing, and translation. DNA replication occurs in the nucleus because DNA is located in the nucleus, and transcription, the process of creating a temporary RNA copy of the...
