What is the termination sequence in transcription?
termination sequence. The sequence of DNA which signals the transcription to stop. in the gene (Fig. 11). The termination sequences signal the end of the gene and can work in a number of ways.
What are the two types of transcription termination?
There are two types of transcriptional termination in prokaryotes, rho-dependent termination and intrinsic termination (also called Rho-independent termination).
How is the termination of transcription different in prokaryotes and eukaryotes?
Eukaryotes contain mRNAs that are monocystronic. Termination in prokaryotes is done by either rho-dependent or rho-independent mechanisms. In eukaryotes transcription is terminated by two elements: a poly(A) signal and a downstream terminator sequence (7).
What initiation and termination factors are involved in transcription in prokaryotes?
Sigma factor is responsible for initiation of transcription. Rho factor is responsible for termination of transcription.
Does transcription occur in prokaryotes?
Prokaryotic transcription is the process in which messenger RNA transcripts of genetic material in prokaryotes are produced, to be translated for the production of proteins. Prokaryotic transcription occurs in the cytoplasm alongside translation. Prokaryotic transcription and translation can occur simultaneously.
How is transcription in prokaryotes different from eukaryotes?
These were a few differences between prokaryotic and eukaryotic transcription….Prokaryotic vs Eukaryotic Transcription.
| Prokaryotic Transcription | Eukaryotic Transcription |
|---|---|
| Doesn’t require any proteins or other factors for the initiation of transcription | Requires proteins known as transcription factors for the initiation. |
Which of the following statement best describes the termination of transcription in prokaryotes?
Which of the following statements best describes the termination of transcription in prokaryotes? RNA polymerase transcribes through the terminator sequence, causing the polymerase to separate from the DNA and release the transcript. RNA polymerase in a prokaryote is composed of several subunits.
How does termination occur in prokaryotes?
Termination in Prokaryotes Near the end of the gene, the polymerase encounters a run of G nucleotides on the DNA template and it stalls. As a result, the rho protein collides with the polymerase. Rho-independent termination is controlled by specific sequences in the DNA template strand.
What describes the termination of transcription in prokaryotes quizlet?
Terms in this set (12) Which of the following statements best describes the termination of transcription in prokaryotes? RNA polymerase transcribes through the terminator sequence, causing the polymerase to separate from the DNA and release the transcript. RNA polymerase in a prokaryote is composed of several subunits.
Which of following describes the process of transcription?
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
