Amino Acid Specific Transfer RNA is spelled "əˈmiːnəʊ ˈæsɪd spəˈsɪfɪk ˈtrænsfər ˈɑːsnə" in IPA phonetic transcription. This term refers to a type of RNA molecule that carries a specific amino acid to a growing peptide chain during protein synthesis. The spelling of this word in IPA transcription accurately represents the pronunciation of each syllable and sound within the word. Understanding IPA phonetics allows for clear communication and accurate spelling of complex scientific terminology.
Amino Acid Specific Transfer RNA, often abbreviated as aa-tRNA, refers to a class of molecules that play a crucial role in protein synthesis within living organisms. These molecules contain genetic information and act as carriers that link the genetic code in DNA or mRNA to the corresponding amino acids during the process of translation.
Transfer RNA (tRNA) is a small RNA molecule comprised of about 70-90 nucleotides. Amino Acid Specific tRNA are a subclass of tRNA molecules that specifically bind to a particular amino acid and carry it to the ribosome, the cellular machinery responsible for synthesizing proteins.
Each amino acid has a specific tRNA molecule associated with it, forming an amino acid-tRNA complex. The specific recognition between tRNA and amino acid is facilitated by an enzyme called aminoacyl-tRNA synthetase, which connects the correct amino acid to its corresponding tRNA molecule.
During translation, the ribosome reads the mRNA sequence and matches each codon with its complementary anticodon on the tRNA molecule. This allows the ribosome to assemble the amino acids in the correct sequence, forming a polypeptide chain that eventually folds into a functional protein.
The highly specific nature of amino acid specific tRNA ensures that the correct amino acid is incorporated into the growing protein chain, contributing to accurate protein synthesis and the maintenance of cellular functions.
