Concept explainers
Which statement describes a difference between transcription in eukaryotic and prokaryotic cells?
In eukaryotes, transcription occurs simultaneously with translation, while transcription in prokaryotes must complete before translation can begin.
In eukaryotes, transcription is completed by an RNA polymerase, while transcription in prokaryotes is completed with a DNA polymerase.
In eukaryotes, transcription produces an RNA molecule, while transcription in prokaryotes produces a DNA molecule.
In eukaryotes, transcription produces a monocistronic RNA, while transcription in prokaryotes produces a polycistronic RNA.
In eukaryotes, transcription produces an DNA molecule, while transcription in prokaryotes produces a RNA molecule.

- During the transcription elongation step, an internal structure in the RNA Polymerase called _______________________ guides the template and non-template DNA strands through channels inside the enzyme. rudder alpha sigma flap zipperarrow_forwardDescribe the structure of RNA polymerase. Explain how this enzyme begins theprocess of transcription in prokaryotesarrow_forwardAnswer based on the question above: You have isolated a new eukaryotic microorganism and want to determine the genetic code of its mitochondria. Here are the amino acids encoded after translation of two synthetic mRNAs using mitochondrial extracts from your eukaryote- in this experiment translation can start at any sequence position: RNA: Protein: UAUAUAUAUAUAUAU--- Tyr-Met-Tyr-Met-Tyr-Met---- UAAUAAUAAUAAUAA--- Asn-Asn-Asn-Asn-Asn---- Met-Met-Met-Met-Met---- Based on the results shown here, what can you conclude about the codons in this eukaryote? AUA UAU UAA AAU A. Tyr Met Asn Met B. Met Tyr Asn Trp C. Tyr Met Asn Asn D. Met Tyr Asn, STOP or Met Asn, STOP or Met O O O B OAarrow_forward

Which of these has a role that is most similar to that of the transcription start site during transcription?
