During eukaryote transcription initiation, when TFIIE, TFIIA, TFIIB, TFIIF, and RNA pol II all join on the DNA strand, how do they know where to be put on the strand?

Identify the labeled factors in the figure below (A and B) and indicate the direction of transcription. ts A O A= Mediator, B= TFIID; direction is into the screen O A= TEIIE, B= TFIIH; direction is into the screen rences A= TBP, B= TEIIB; direction is out of the screen O A= TFIIF, B= TFIIE; direction is out of the screen

in a eukaryote cell, what do we call the DNA sequence that the specific transcription factor binds to

7) Which of the following needs to occur for transcription to take place in prokaryotes? A) The RNA polymerase must recognize the promotor sites that typically occur upstream of the start of transcription at approximately -35 and -10 base pairs. B) The sigma factor protein must be absent for RNA polymerase to bind to the promotor site. C) An enhancer site must be activated upstream of the promotor site. D) Molecules outside the nucleus must trigger transcription factors located on the DNA. X X X XX Homologous chromosomes can line up in two ways during metaphase of mesosial 1000 8) The image above demonstrates A) linked genes X B) the principle of independent assortment C) the central dogma of molecular biology D) the law of dominance XX X 9) Which of the following statements is true? A) A recessive trait will never be the most common phenotype in a population, regardless of environment. CB Dominant traits are always the most common phenotype in a population, regardless of environment.…
