How is the initiation of transcription different in prokaryotes and eukaryotes?
The main difference between prokaryotic transcription and eukaryotic transcription is that the prokaryotic transcription process occurs in the cytoplasm, while the eukaryotic transcription process occurs in the nucleus.
What are two differences between initiation of prokaryotic and eukaryotic translation?
In the process of translation, the nucleotide triplets, referred to as codons, present on the mRNA will be translated into an amino acid sequence….Difference Between Prokaryotic And Eukaryotic Translation.

How does initiation during transcription differ between prokaryotes and eukaryotes quizlet?
In a eukaryotic cell, transcription occurs in the nucleus, and translation occurs in the cytoplasm. In a prokaryotic cell, transcription and translation are coupled; that is, translation begins while the mRNA is still being synthesized.
What is a major difference in how eukaryotes and prokaryotes select an Aug to initiate translation?
Another main difference between the two is that transcription and translation occurs simultaneously in prokaryotes and in eukaryotes the RNA is first transcribed in the nucleus and then translated in the cytoplasm.
Are there differences in initiation of protein synthesis between prokaryotes and eukaryotes?
In eukaryotes, genes have introns (intervening sequences) and exons (coding sequence) but in prokaryotes intron sequences are absent. In prokaryotes, three initiation factors are involved, whereas eukaryotes have nine initiation factors involved in a pre-initiation complex.
How does transcription inhibition differ between prokaryotes and eukaryotes quizlet?
Transcription inhibition differs between prokaryotes and eukaryotes since eukaryotes have a higher number of transcription factors that regulate more genes in comparison to prokaryotes.
What is the primary difference between prokaryotic and eukaryotic translation?
Main Differences Between Prokaryotic and Eukaryotic Translation. The prokaryotic translation is a simultaneous process, whereas eukaryotic translation is not simultaneous and it is a discontinuous process. In prokaryotic translation, the ribosomes involved are the 30S and 50S ribosomes.
Which of the following is required for transcription initiation in eukaryotes?
Like prokaryotic cells, the transcription of genes in eukaryotes requires the action of an RNA polymerase to bind to a DNA sequence upstream of a gene in order to initiate transcription.
What are some differences in the way that eukaryotes and prokaryotes handle DNA replication transcription & translation Why do these differences exist?
In prokaryotic cells, there is only one point of origin, replication occurs in two opposing directions at the same time, and takes place in the cell cytoplasm. Eukaryotic cells on the other hand, have multiple points of origin, and use unidirectional replication within the nucleus of the cell.
Why is protein synthesis different in prokaryotes?
The process of protein synthesis is faster in prokaryotes as the whole process takes place in the cytoplasm. In eukaryotes it is slower because the pre- mRNA is first synthesized in the nucleus and after splicing, the mature mRNA comes to the cytoplasm for translation.
What must eukaryotes do to initiate transcription of a gene?
The Promoter and the Transcription Machinery. Genes are organized to make the control of gene expression easier.
What are the six steps of translation in eukaryotes?
I. binding of mRNA to ribosome.
How is transcription terminated in eukaryotes?
Termination of Eukaryotic Transcription By Chain Cleavage And The Addition Of 3 Poly(A) Tails. The three ends of the transcripts made via RNA polymerase II are produced by endonucleolytic degradation of primary transcripts , not by the end of transcription. The actual termination of transcription events typically occur at multiple locations
How to inhibit eukaryotic transcription?
enhancer: a short region of DNA that can increase transcription of genes
