Question

Which provides the best general model of how transcription starts for eukaryotic genes? a. Activators and general transcription factors bind to promoters. RNA polymerase then binds to an enhancer to start transcription. b. RNA polymerase binds directly to a promoter and begins transcription. Activators and general transcription factors bind later and increase the rate of transcription. c. General transcription factors bind to a promoter and recruit RNA polymerase. Activators bound to enhancers help transcription begin. d. RNA polymerase binds directly to the AUG start codon. Activators and general transcription factors then bind to enhancers to help transcription begin. Which of the following statements describes why splicing is used in eukaryotes? a. Splicing is required for transcription termination. b. Splicing is required to put in a start codon so that ribosomes can start translation c. Splicing a gene in different ways can result in multiple types of proteins

Explanation / Answer

ANSWER:

8) RNA polymerase binds directly to a promoter and begins transcription.Activators and general transcription factors binds later and increase the rate of transcription.

9) Splicing a gene in different ways can result in multiple types of proteins produced from the same gene.
