tRNATyr refers to a transfer RNA molecule that carries the amino acid Tyrosine during protein synthesis. The spelling of tRNATyr is based on the abbreviations for transfer RNA (tRNA) and the amino acid Tyrosine (Tyr). The phonetic transcription of tRNATyr in IPA is /tiː ɑːr ɛn ˈeɪ ˈtaɪr/. This can be broken down into four parts: "tee" represents the sound of the letter T, "ahr" for R, "en" for N, and "eye" for Tyrosine (Tyr).
tRNATyr, also known as transfer RNA for Tyrosine, is a specific type of ribonucleic acid (RNA) molecule that plays a crucial role in the process of protein synthesis. It is one of the many transfer RNA molecules that exist in living organisms, responsible for carrying the amino acid tyrosine to the ribosomes, where proteins are synthesized.
This particular tRNA molecule contains a specific sequence of nucleotides that is complementary to the codon sequence found on the messenger RNA (mRNA), which is responsible for encoding the amino acid sequence in a protein. The tRNATyr molecule has an anticodon region, a part of the molecule that recognizes and binds to the complementary codon on the mRNA.
When the mRNA sequence encodes for the amino acid tyrosine, the tRNATyr molecule with the corresponding anticodon sequence is recruited. The amino acid tyrosine then becomes attached to the tRNA molecule through a chemical bond. This loaded tRNATyr molecule then moves to the ribosome where the codon and anticodon recognition occurs.
Once at the ribosome, the tRNATyr molecule binds to the corresponding codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing polypeptide chain during protein synthesis. This process continues until the entire protein chain is synthesized.
Overall, tRNATyr is an essential component of the molecular machinery involved in protein synthesis, ensuring the accurate incorporation of the amino acid tyrosine into proteins.
The term "tRNATyr" is a combination of two parts: "tRNA" and "Tyr".
1. tRNA: "tRNA" stands for "transfer ribonucleic acid". The abbreviation "tRNA" was coined in the early 1960s when the structure and function of these molecules were being studied. The "t" in "tRNA" refers to "transfer", indicating its role in transferring amino acids during protein synthesis. The term "RNA" indicates that it is a type of ribonucleic acid.
2. Tyr: "Tyr" stands for tyrosine, which is an amino acid. It is one of the 20 standard amino acids that make up proteins. The term "Tyr" is derived from the full name of the amino acid, "tyrosine".
