Q is similar to N in its effect: Q binds to RNA polymerase in Qut sites and the resulting complex can ignore terminators, however the mechanism is very different; the Q protein first associates with a DNA sequence rather than an mRNA sequence.
Q ten uns efectos similares aos de N: Q únese á ARN polimerase nos sitios Qut e o complexo resultante pode ignorar terminadores, aínda que o mecanismo é moi diferente; a proteína Q asóciase primeiro cunha secuencia de ADN en vez de cunha secuencia de ARNm.
