How is translation different in bacteria and eukaryotes?
Eukaryotic and Prokaryotic translations are involved in protein synthesis. The key difference between eukaryotic and prokaryotic translation is that eukaryotic translation and transcription is an asynchronous process whereas prokaryotic translation and transcription is a synchronous process.
Can bacteria translate eukaryotes?
Unlike eukaryotic cells, bacteria do not have a distinct nucleus that separates DNA from ribosomes, so there is no barrier to immediate translation. This process simply would not work in eukaryotic cells, mainly because eukaryotic RNAs contain introns and exons and must be edited before translation can begin.
What happens during translation in eukaryotes?
Translation involves translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. It is the process in which ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA.
How translation is terminated in eukaryotes and in bacteria?
EUKARYOTIC TRANSLATION TERMINATION. Translation termination takes place when the end of the coding sequence is reached by the ribosome and a stop codon (UAA, UGA, or UAG) enters the A site. The class I factor, eRF1, is responsible for high-fidelity stop codon recognition and peptidyl-tRNA hydrolysis.
Is statement true of translation in both 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.
What is the process of bacterial translation?
Bacterial translation is the process by which messenger RNA is translated into proteins in bacteria.
How is the process of translation terminated?
Translation ends in a process called termination. Termination happens when a stop codon in the mRNA (UAA, UAG, or UGA) enters the A site. After the small and large ribosomal subunits separate from the mRNA and from each other, each element can (and usually quickly does) take part in another round of translation.
What is the process of translation?
Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes.
What happens at the beginning of translation?
Translation begins when an initiator tRNA anticodon recognizes a codon on mRNA. The large ribosomal subunit joins the small subunit, and a second tRNA is recruited. As the mRNA moves relative to the ribosome, the polypeptide chain is formed.
Where does translation occur in the eukaryotic cell?
1. Site: Translation occurs in the cytoplasm where the ribosomes are located. Ribosomes are made of a small and large subunit which surrounds the mRNA. In eukaryotic translation 80S ribosomes with 40S and 60S subunits are used. The mRNA is synthesized from DNA only. In eukaryotes, there is single initiation and termination site.
How is translation initiation carried out in bacteria?
In bacteria, translation initiation occurs as soon as the 5′ end of an mRNA is synthesized, and translation and transcription are coupled. This tight coupling is not possible in eukaryotes because transcription and translation are carried out in separate compartments of the cell (the nucleus and cytoplasm).
How is the primary transcript used in prokaryotes?
(A) In prokaryotes, the primary transcript serves as mRNA and is used immediately as the template for protein synthesis. (B) In eukaryotes, mRNA precursors are processed and spliced in the nucleus before being transported to the cytosol for translation into protein.
How are prokaryotes mRNAs different from eukaryote transcripts?
Unlike the eukaryote transcript, this mRNA does not have to be transported a long distance and thus does not encounter various enzymes that are likely to degrade it. As a result, the mRNA in prokaryotes does not require additional protection to prevent damage.
