RNA transcripts. incorporation rRNA transmembrane mRNA snRNA tRNA pRNA transcription proteins translation 7-4 Match the following structures with their names. Figure Q7-4 7-5 Which of the following statements is false? (a) A new RNA molecule can begin to be synthesized from a gene before the previous RNA molecule’s synthesis is completed. (b) If two genes are to be expressed in a cell, these two genes can be transcribed with different efficiencies. (c) RNA polymerase is responsible for both unwinding the DNA helix and catalyzing the formation of the phosphodiester bonds between nucleotides. (d) Unlike DNA, RNA uses a uracil base and a deoxyribose sugar. 7-6 Which one of the following is the main reason that a typical eucaryotic gene is able to respond to a far greater variety of regulatory signals than a typical procaryotic gene or operon? (a) Eucaryotes have three types of RNA polymerase. (b) Eucaryotic RNA polymerases require general transcription factors. (c) The transcription of a eucaryotic gene can be influenced by proteins that bind far from the promoter. (d) Procaryotic genes are packaged into nucleosomes. 7-7 Match the following types of RNA with the main polymerase that transcribes them. 7-8 List three ways in which the process of eucaryotic transcription differs from the process of bacterial transcription. 7-9 For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase should be used only once. In eucaryotic cells, general transcription factors are required for the activity of all promoters transcribed by RNA polymerase II.
