Which rnas are needed for translation
During translation, an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated into the letter code of amino acids, which are the building blocks of proteins. The genetic code is a set of three-letter combinations of nucleotides called codons, each of which corresponds with a specific amino acid or stop signal.
Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. The ribosome has a small and a large subunit and is a complex molecule composed of several ribosomal RNA molecules and a number of proteins. Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination.
At least one type of aminoacyl tRNA synthetase exists for each of the 20 amino acids. Did you have an idea for improving this content? Improve this page Learn More. Skip to main content. Search for:.

The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA.
