When Does Translation Occur

Translation is one of many steps in the creation of protein which is needed to fuel the body. In prokaryotes translation occurs directly after transcription.

Translation involves the mrna trna and rrna coming together.

When does translation occur. In translation messenger rna mrna is decoded in a ribosome outside the nucleus to produce a specific amino acid chain or polypeptide. After leaving the nucleus mrna must undergo several modifications before being translated. Where does translation occur.

70s for prokaryotic ribosomes whereas 80s for eukaryotic ribosomes. In both eukaryotic cells translation protein synthesis occur in the ribosomes. Translation occurs in the cell specifically in the cytoplasm.

The mrna goes through the rrna starting at the end identified as 5 or the end with a u g and it will go all the way through to the terminating end. This process is initiated when the dna molecule uncoils its strands by breaking the hydrogen bonds which hold the complementary base pairs together. In molecular biology and genetics translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process transcription of dna to rna in the cell s nucleus the entire process is called gene expression.

Sections of the mrna that do not code for amino acids called introns are removed. Mainly composed of rna and proteins ribosomes are characterized by their rates of sedimentation. In some cases translation of one end of an mrna strand can begin while the other end is still being transcribed.

The translation takes place and thus completes the process of protein synthesis. In eukaryotes translation occurs entirely separately from transcription because pre mrna script created in transcription must be modified before its translated. Translation occurs in the cytoplasm.
