The term "Isoleucine Specific tRNA" is pronounced as /ˌaɪsəˈluːsiːn spɛsɪfɪk ti: ɑːr en/ according to IPA phonetic transcription. "Isoleucine" is spelled with the letter "i" followed by "s" and "o", while "leucine" is spelled with "l" and "eu." "Specific" is spelled with "s," and "tRNA" is spelled with the letter "t" followed by "RNA." This term is used in the field of biochemistry to refer to a type of transfer RNA that specifically binds to isoleucine, an amino acid used in protein synthesis.
Isoleucine specific tRNA, also known as Iso-tRNA, is a type of transfer RNA (tRNA) molecule that specifically binds to and carries the amino acid isoleucine during protein synthesis. tRNA molecules are essential components of the cellular machinery responsible for translating the genetic code encoded in messenger RNA (mRNA) into functional proteins.
The amino acid isoleucine is one of the twenty standard amino acids that are used by cells to build proteins. These amino acids must be brought to the ribosome, the site of protein synthesis, in order to be incorporated into the growing polypeptide chain. Isoleucine specific tRNA molecules play a crucial role in this process by recognizing the specific codon sequence for isoleucine on the mRNA. The tRNA molecule possesses an anticodon sequence that complements the mRNA codon, ensuring accurate pairing.
Isoleucine specific tRNA molecules have a specific structure that allows them to transport isoleucine to the ribosome. They are composed of a cloverleaf-shaped molecule, with three hairpin loops that contain the anticodon sequence, and a binding site for isoleucine. This binding site is critical for the specific recognition and attachment of isoleucine to the tRNA molecule.
Overall, isoleucine specific tRNA molecules are essential for the precise incorporation of isoleucine into proteins during translation. They serve as molecular adaptors, ensuring the accurate recognition of the isoleucine codon on the mRNA and facilitating the correct incorporation of isoleucine into the growing polypeptide chain.
