A scientist observing a cell during gene expression would be able to easily distinguish it as a prokaryotic cell by which of the following observations? Group of answer choices as soon as the DNA introns are removed from the template after the 5' caps are converted to mRNA after a transcription initiation complex has been formed during transcription once the pre-mRNA has been converted to mRNA

Choose all that apply regarding gene transcription in eukaryotes: Exons are removed from mRNA by the spliceosome. RNA polymerase II must completely finish an mRNA transcript before processing can begin. RNA polymerase I catalyzes the synthesis of the majority of ribosomal RNA. Histone acetylation is a method of controlling gene expression. Acetylation creates more positive charges on histones, leading to tighter binding of the proteins to DNA. Introns must be removed from the initial RNA transcript. The hormone 17beta-estradiol binds to a G-protein coupled receptor to control gene transcription. The 5' cap of mRNA requires the free triphosphate on the nucleotide at the 5' end. Multiple transcription factors are necessary to form the pre-initiation complex (PIC) of RNA Pol II.

Ⓒ Macmillan Learning Classify the given examples of prokaryotic gene expression as positive or negative gene regulation. 54 $ R In the presence of excess tryptophan, a repressor protein binds the operator of the trp operon and prevents the operon from being transcribed. In the absence of lactose, the lacR repressor protein binds the lac operon. F4 Positive gene regulation In the presence of the sugar arabinose, an activator protein binds the promoter of the genes responsible for processing arabinose and induces their transcription. In the presence of iron, the dtxR repressor protein binds DNA, and the gene that encodes for the diphtheria toxin is not expressed. % 5 In the presence of lactose and low glucose, the lac operon expressed 20-fold higher than in the absence of lactose.
