What are the basic steps of translation?
Translation is the process by which the genetic code contained within a messenger RNA (mRNA) molecule is decoded to produce a specific sequence of amino acids in a polypeptide chain. It occurs in the cytoplasm following DNA transcription and, like transcription, has three stages: initiation, elongation and termination.
What are the six steps of translation?
Terms in this set (6)
- mRNA leaves the nucleus and migrates to ribosome.
- mRNA binds to small ribosomal subunit.
- tRNA brings an amino acid to the ribosome, where anticodon on the tRNA binds to the codon of the mRNA.
- The amino acid bonds to its adjoining amino acid to form a growing polypeptide molecule.
What is 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 does translation in cell mean?
Listen to pronunciation. (trans-LAY-shun) In biology, the process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). The mRNA is made by copying DNA, and the information it carries tells the cell how to link amino acids together to form proteins.
What are the steps in the translation of DNA?
DNA Translation Steps Steps of Translation Each cell makes the proteins that contain the right set of amino acids, link with each other in the right order. A cell builds proteins by using four stages of the translation; initiation, elongation, and termination, epilogue. � � 1.
When does translation occur in a prokaryotic cell?
In both prokaryotic and eukaryotic cells, translation occurs in three major stages: initiation, elongation, and termination. During initiation, the first step to occur is the binding of a specific initiator methionyl tRNA and mRNA to the small ribosomal subunit.
What are the names of the three stages of translation?
Translation has pretty much the same three parts, but they have fancier names: initiation, elongation, and termination. Initiation (“beginning”): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin.
What do you need to start the translation process?
In order for translation to start, we need a few key ingredients. These include: An “initiator” tRNA carrying the first amino acid in the protein, which is almost always methionine (Met) During initiation, these pieces must come together in just the right way.
