Which of the following types of RNA is found exclusively in eukaryotic cells? snRNA snRNAs are involved in mRNA splicing in the nuclei of eukaryotic cells. This process does not take place in prokaryotes. 2. Which of the following is a property of the RNA polymerase holoenzyme, but not the core polymerase, in E. coli? promoter recognition and binding The RNA polymerase holoenzyme specifically recognizes and binds to promoters due to the activity of sigma factor. Sigma factor is not a component of the core polymerase. 3. The same DNA strand is used as the template strand for all of the genes that are located on a single eukaryotic chromosome. false For a given gene, only one of the two strands serves as the template strand. However, the orientation of genes on the chromosome varies from one gene to the next, so adjacent genes may utilize different strands of the DNA duplex as their templates. 4. Which of the following is the first step in nuclear mRNA splicing? [Show More]
