(A) Binding to an extracellular ligand (B) Binding of the protein to other transmembrane proteins (C) Increased temperature (D) Protease cleavage of the cytosolic domain of the protein (E) Protease cleavage of the extracellular domain of the protein

37. Which of the following is correct regarding both Cas9 and EcoRI?(1) They are both endonucleases.(2) They both create double-strand breaks in DNA.(3) They both recognize their target sequences with the help of guide RNAs.(4) They are both part of bacterial defense mechanisms against foreign DNA.(5) They are both greatly useful in manipulating DNA and studying gene expression. (A) 1 only (B) 1,2 and 5 (C) 2,3 and 5 (D) 1, 2, 4 and 5 (E) All

38. All are true for transcription activation except: (A) takes place when a transcriptional activator protein bound to DNA makes protein : protein contacts with RNA polymerase. (B) the degree of transcriptional activation is proportional to the strength of the protein : protein interaction. (C) a nucleotide sequence binding site for a DNA-binding protein serves as an activator site if DNA-binding protein can interact with promoter-bound RNA polymerase. (D) if the DNA-bound transcriptional activator makes contact with two different components of RNA polymerase, the transcription is markedly elevated. (E) All are true.

39. Which one of the following does not contribute to the activation of transcription in eurkaryotes? (A) SWISNF chromatin remodeling proteins (B) Histone acetyltransferases (C) Histone methylases (D) Histone deacetylases (E) Alterations in histone content

40. Enzymes that acetylate the s-amino group of lysine in the histidine tails are called_____and are involved in________. (A) histone deacetylases； restoring chromatin to a repressed state (B) histone acety1transferases (HATs)； initial events in transcriptional activation (C) histone activases； formation of the de-repression complex (D) Schiff base formation； promoting the formation of closed complexes (E) None of the above
