tRNA is involved in the translation of the nucleic acid message into the amino acids of proteins. tRNA itself is an RNA molecule with a conserved inverted L structure. One end of the tRNA contains an anticodon loop which pairs with a mRNA specifying a certain amino acid. The other end of the tRNA has the amino acid attached to the 3' OH group via an ester linkage.
tRNA with an attached amino acid is said to be "charged". The enzyme that attaches the amino acid to the 3'-OH is called an aminoacyl tRNA synthetase (aaRS). There is a specific tRNA for each amino acid, 20 in all. Similarly, there is a specific aaRS for each tRNA.
Only the first 2 nucleotides in the tRNA anticodon loop are strictly required for the decoding of the mRNA codon into an amino acid. The third nucleotide in the anticodon is less stringent in its base-pairing to the codon, and is referred to as the "wobble" base. Since the genetic code is degenerate, meaning that more than one codon can specify a single amino acid, the anticodon of tRNA can pair with more than one mRNA codon and still be specific for a single amino acid.
What else can I help you with?
What do the circles of the tRNA represent?
The circles in tRNA represent the secondary structure of the molecule, which consists of a cloverleaf shape with loops and stems. Each circle corresponds to a segment of the tRNA molecule, including the acceptor arm, amino acid arm, D loop, T loop, and anticodon loop. These elements are essential for the proper function of tRNA in protein synthesis.
What does each tRNA carries in the process of protein synthesis?
Transfer RNA (tRNA) molecules carry specific amino acids to the ribosome during protein synthesis. Each tRNA has an anticodon that pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is added to the growing polypeptide chain.
What anticodon pairs with the codon gau?
The anticodon that pairs with the codon GAU is CUA. This is based on the rules of complementary base pairing in DNA and RNA.
What is the anticodon for CGA?
A pairs with T so the anticodon would be TTT
What are the two functional parts of a changed tRNA?
The two functional parts of a tRNA molecule are the anticodon loop, which pairs with the mRNA codon during translation, and the amino acid attachment site, where the specific amino acid corresponding to the tRNA is bound.

These elements are essential for the proper function of tRNA in protein synthesis.
What part of tRNA should match the codon of the mRNA?
The anticodon loop of tRNA should match the codon of the mRNA during translation. The anticodon is a sequence of three nucleotides on tRNA that is complementary to the codon on mRNA, allowing for the correct amino acid to be brought to the ribosome during protein synthesis.
What is the structure function and location of anticodon?
The anticodon is a sequence of three nucleotides found on transfer RNA (tRNA) molecules. Its function is to base pair with a complementary codon on messenger RNA (mRNA) during translation. The location of the anticodon is within the loop region of the tRNA molecule.
What does each tRNA carries in the process of protein synthesis?
Transfer RNA (tRNA) molecules carry specific amino acids to the ribosome during protein synthesis. Each tRNA has an anticodon that pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is added to the growing polypeptide chain.
Each tRna carries three special nucleotides that are referred to as the?
the three special nucleotide sequences are anticodon loop,dloop and aminoacid acceptor arm
Where is the anticodon site on a tRNA molecule?
The anticodon site on a tRNA molecule is located at one end of the tRNA structure, specifically on the loop region of the cloverleaf shape. This site contains a sequence of three nucleotides that are complementary to the codon on the mRNA, allowing for proper pairing during protein synthesis. The anticodon plays a crucial role in ensuring that the correct amino acid is added to the growing polypeptide chain.
What anticodon pairs with the codon gau?
The anticodon that pairs with the codon GAU is CUA. This is based on the rules of complementary base pairing in DNA and RNA.
What contains the anticodon and binds to a particular amino acid?
tRNA contains the anticodon
What is the anticodon for CGA?
A pairs with T so the anticodon would be TTT
What are the two functional parts of a changed tRNA?
The two functional parts of a tRNA molecule are the anticodon loop, which pairs with the mRNA codon during translation, and the amino acid attachment site, where the specific amino acid corresponding to the tRNA is bound.
The three bases on the tRNA molecule that are complementary to one of the mRNA codons are called the?
putos - what in the hell is putos? it sounds NASTY
What does the structure tRNA look like?
tRNA is a single-stranded RNA molecule that folds into a cloverleaf-like structure with several loops and stems. It contains three hairpin loops: the anticodon loop, the D loop, and the TΨC loop. The anticodon loop is key for recognizing and binding the complementary mRNA codon during protein synthesis.
