查询词典 transcription

Attenuation vs repression The trp operon is regulated by both repression(which determines whether transcription will occur or not)and attenuation.Other operons for amino acid biosynthetic pathways may also be regulated by both repression and attenuation or only by attenuation.

弱化作用与阻遏作用的比较 trp操纵子同时受到弱化作用和阻碍作用的调控，其他氨基酸生物合成途径的操纵子也可能受弱化作用和阻碍作用的调控，或者仅有弱化作用调控。
