Question

In eukaryotes, gene expression is not regulated by a protein complex formed between transcription factors and RNA polymerase.

(a) True

(b) False

I had been asked this question by my school principal while I was bunking the class.

My doubt is from Promoter and Regulatory Elements in Prokaryotes & Eukaryotes topic in chapter Promoter and Regulatory Element Prediction of Bioinformatics

Answer 1

Right choice is (b) False

Best explanation: Here, the gene expression is also regulated by a protein complex formed between transcription factors and RNA polymerase. However, eukaryotic transcription has an added layer of complexity in that there are three different types of RNA polymerase complexes, namely RNA polymerases I, II, and III.
