RNA: transcription and processing

6 important questions on RNA: transcription and processing

Protein tail of the RNApolII that coordinates processing of the pre-mRNA including capping, splicing and termination:

Carboxyterminaldomain

Complex formed by general transcription factors and the RNApolII

Pic

Transcription of information from DNA to RNA is based on 2 principles. What are these principles?

  1. The matching of complementary bases
  2. The binding of various proteins to specific sites on the RNA or DNA

Mention four important differences between RNA and DNA

  1. Ribose/Deoxyribose
  2. Uracil/Thynine
  3. Single-stranded/Double-stranded
  4. RNA can catalyze biological reactions (ribozyme)

What are the two general classes of RNA?

  • Messenger RNA (mRNA)
  • Functional RNA

What is the function of a TATA-box?

It is the site of the first event in transcription: the binding of the TATA-binding protein TBP.  The TBP is part of the TFIID complex, one of the six GTFs. When bound to the TATA box, TBP attracts other GTFs and the RNA polymerase II core to the promoter, thus forming the PIC.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
