有.轉(zhuǎn)錄泡是指與RNA聚合酶結(jié)合的DNA局部解鏈區(qū).原核和真核生物的DNA在進(jìn)行轉(zhuǎn)錄活動(dòng)時(shí)都是局部解鏈,形成轉(zhuǎn)錄泡結(jié)構(gòu).
轉(zhuǎn)錄泡（Transcription bubble）的英文解釋：
is a molecular structure that occurs during the transcription or replication of DNA when DNA helicase and DNA topoisomerase "unzip" the DNA double strand. DNA polymerase or RNA polymerase (Main Articles: DNA replication, transcription) may then bind to the exposed DNA and begin synthesizing a new strand of DNA or RNA. As DNA and/or RNA polymerase progresses down the DNA strand in the 5' to 3' direction, more of the DNA double strand is unwound, creating a replication or transcription bubble in the process that may be seen with specialized staining techniques and microscopy.
