Question

In eukaryotic protein-encoding genes, three categories of proteins are required for basal transcription at the core promoter: RNA polymerase ___ , general transcription ____ , and a complex called mediator.

Answer 1

Three categories of proteins required for basal transcription at the core promoter in eukaryotic protein-encoding genes are RNA polymerase II, general transcription factors, and the mediator complex.

Step-by-step explanation:

In eukaryotic protein-encoding genes, three categories of proteins are required for basal transcription at the core promoter. These are RNA polymerase II, general transcription factors, and the mediator complex.

RNA polymerase II is the enzyme responsible for synthesizing the mRNA from the DNA template. It cannot initiate transcription on its own and requires the assistance of general transcription factors, which help to recruit RNA polymerase II to the promoter region. The mediator complex acts as a bridge between the general transcription factors and RNA polymerase II, facilitating the initiation of transcription.
