Which of the following describes the correct stepwise assembly (in vitro) of the eukaryotic RNA polymerase II preinitiation comp

PilotLPTM [1.2K]

Answer: (TFIID) TBP-> TFIIB IIA--> TFIIF RNA POL II

Explanation:

Remember that in eukaryotic organisms, transcription and processing are coupled processes. There are 3 different types of Rna pol. In the case of RNA pol II transcribes genes that encode proteins (mRNA synthesis). Transcription factors are involved, for example: TFIID, TBPs, TAF (recognizes TATA promoter center, regulatory functions), TFIIA (stabilizes TBP union, antirepressant function), TFIIB (RNA Pol II starting point selection).

What is synthesized from the DNA template? This is used to assemble ______ into ______.

Vladimir79 [104]

Answer:
The right option for blanks is mRNA, amino acids and polypeptide chain (protein).

Reason:
During protein synthesis first of all mRNA formation occurs from DNA template. Then mRNA come out from nucleus into cytoplasm and bind with ribosome, where tRNA come and binds to mRNA codon with the help of anticodons. and add amino acids. In this way a chain of polypeptide is formed.
