Final answer:
Basal transcription factors, including TFIIB, are essential in the formation of the preinitiation complex for the initiation of transcription in eukaryotes, which encompasses insect species as well.
Step-by-step explanation:
The statement presented in the question suggests that there is no evidence that the basal transcription factor TFIIB is used in the regulation of histone gene transcription in insects. It is important to clarify that basal transcription factors, including TFIIB, are a key part of the preinitiation complex that recruits RNA polymerase II for the initiation of transcription in eukaryotes, which includes insects. The complexity of eukaryotic transcription involves multiple components such as regulatory sequences, like the TATA box, and transcription factors, including TFIID and enhancers and silencers. While enhancers and silencers are not necessary for the transcription to proceed, the preinitiation complex formed with the aid of basal transcription factors is critical for starting the transcription process.
