Sep 8, 2023 · Biology definition: Translation is the process of translating (converting) the transcript (genetic information) from the mRNA into a specific sequence of amino acids in the growing chain of a polypeptide. The three general steps of translation are initiation, translation elongation, and translation termination.
Apr 7, 2019 · Translation Definition. Translation refers to the process of creating proteins from an mRNA template. The sequence of nucleotides on the RNA is translated into the amino acid sequence of proteins and this reaction is carried out by ribosomes.

- No. The ribosome is the workbench and the mRNA is being moved through the ribosome shifting downwards every codon.
- IF1, Binds to the 30S subunit to the A site, prevents tRNA binding IF2, Binds initiator tRNA (f-Met) and controls its entry to the ribosome at the...
- They don't get translated! The 5' UTR is everything 5' of the start codon. The interesting question is how does the ribosome know which start codon...

- Great question! The tRNA is released into the cell and can again be joined with an amino acid. (Details on the joining are in the previous section.)

- Yes, it is. It cannot be considered start codon if it is not AUG at the beginning of first exon. What might confuse is that it does not have to be...
- There are two things that could happen to it. It could go back to the nucleus to be reused, or, if it is detected to have outlived its usefulness,...
Aug 6, 2024 · Translation, the synthesis of protein from RNA. Translation takes place on ribosomes, where messenger RNA molecules are read and translated into amino acid chains. These chains are then folded in various ways to form proteins. Translation follows transcription, in which DNA is decoded into RNA.

Aug 31, 2020 · Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein. These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic.
Feb 17, 2023 · The first step, called transcription, involves rewriting the information in DNA to mRNA. In contrast, the second step is called translation. Thus the main purpose of translation is to convert the information in mRNA into a particular sequence of amino acids (a polypeptide chain), forming a protein.
