Why Can Translation Begin Before Transcription Is Complete In Prokaryotes But Not In Eukaryotes?

What is the difference between prokaryotic and eukaryotic protein synthesis?

Explanation: Prokaryotic protein synthesis can be fairly fast because one gene can be transcribed and translated simultaneously.

Eukaryotic synthesis is slower, but more precious.

They can “check” the mRNA before it is translated into protein..

What are the 4 steps of protein synthesis?

It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.

Is transcription the same in prokaryotes and eukaryotes?

Eukaryotes have three types of RNA polymerases, I, II, and III, and prokaryotes only have one type. … 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.

Why are transcription and translation separated in eukaryotic cells?

In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that transcription and translation are physically separated.

Is protein synthesis faster in prokaryotes or eukaryotes?

Explanation: Prokaryotic protein synthesis can be fairly fast because one gene can be transcribed and translated simultaneously. Eukaryotic synthesis is slower, but more precious. They can “check” the mRNA before it is translated into protein.

Is translation the same in prokaryotes and eukaryotes?

Translation is a universal process occurs in both prokaryotes and eukaryotes. The fundamental process of translation is same in prokaryotes and eukaryotes. Members of both groups uses information present in mRNA, which is came from the DNA by transcription, to synthesize proteins with ribosome as the machinery.

Which does not occur during translation in eukaryotes?

A difference between bacterial and eukaryotic translation is_____. Modification to the 5′ end of mRNA help to to bind to ribosomes only in eukaryotes. Which of the following does NOT occur during translation in eukaryotes? Introns are removed by the ribosome.

Why can transcription and translation occur simultaneously in prokaryotes but not in eukaryotes?

In eukaryotic cells, transcription happens inside the nucleus and translation can’t happen until the mRNA is transported out into the cytoplasm. … Prokaryotes have no membrane bound organelles such as a nucleus, thus the process of transcription and translation can occur simultaneously.

How does transcription and translation differ in prokaryotes and eukaryotes?

In a prokaryotic cell, transcription and translation are coupled; that is, translation begins while the mRNA is still being synthesized. In a eukaryotic cell, transcription occurs in the nucleus, and translation occurs in the cytoplasm.

Are prokaryotic cells capable of protein synthesis?

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. … Within the nucleus of the cell (light blue), genes (DNA, dark blue) are transcribed into RNA.

What are three differences in transcription between prokaryotes and eukaryotes?

Eukaryotes have three types of RNA polymerases, I, II, and III, and prokaryotes only have one type. … 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.

How is the central dogma different in prokaryotes and eukaryotes?

The Central Dogma in prokaryotic versus eukaryotic cells In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.

What are the 3 stages of translation?

Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.

What happens to a primary transcript in eukaryotic cells before translation can occur?

Left panel: eukaryotic cell. In the nucleus, a pre-mRNA is produced through transcription of a region of DNA from a linear chromosome. This transcript must undergo processing (splicing and addition of 5′ cap and poly-A tail) while it is still in the nucleus in order to become a mature mRNA.
