Every three bases on an mRNA molecule is known as a codon. The tRNA molecules have corresponding base pairs called an anticodon that will only pair up with the codons on mRNA. In this way mRNA specifies the amino acid that tRNA brings next in the sequence on the growing peptide chain.

Why does tRNA have a T shape?
The shape of tRNA is specifically designed to be able to accept the amino acid according to its anticodon. If tRNA was in any other shape, aminoacyl tRNA synthetase, the enzyme that adds amino acid to tRNA, would not be able to transfer the amino acid to tRNA.
What enzyme catalyzes the attachment of an amino acid to tRNA?
The enzyme that catalyzes the attachment of an amino acid to tRNA is aminoacyl-tRNA synthetase.
What is the function of tRNA.?
tRNA mediates recognition of the codon and provides the corresponding amino acid. It mainly is recognized for carrying amino acids. It then gives to it mRNA to translate the nucleotides proteins.
Adds the correct amino acid to the growing protein chain?
tRNA (transfer RNA) attaches to the mRNA by the codon and anticodon.Each tRNA carries an amino acid that corresponds to the codon on the mRNA. This is how the correct amino acid is added to the chain.
When a tRNA anticodon binds to an mRNA codon does the amino acid detach from the tRNA molecule and bond to the end of a growing protein chain?
yes very much so, it's the anti-codon that tells the tRNA which amino acid to go get
Is tRNA attached to an amino acid?
Amino acids are attached to one end of the transfer RNA molecules and the other end of the tRNA moleule attaches to the a-site of the ribosome.

What are the differences between a charged tRNA and an uncharged tRNA?
Well, charged tRNA means it has an amino acid attached. And a charged tRNA can read the codon of mRNA during translation.the charged tRNA mean that the correct amino acid is attached. uncharged means no amino acid is attached. mischarged means the wrong amino acid is attached. if the wrong amino acid is attached then there may be low levels which can cause misfolded proteins.

Where exactly does an amino acid link to a tRNA molecule?
All tRNAs have an amino acid (or acceptor) stem - which is the 3' end and is composed of CCA. The amino acid stem is where the link between the tRNA and the amino acid occurs.
Does tRNA have proteins?
tRNA is a vital molecule that serves as an adapter in protein synthesis. tRNA does have amino acid acceptor arm where an amino acid is presented. But they do not have any protein on them.
What are the differences between charged tRNA and uncharged tRNA?
Charged tRNA has an amino acid attached to it, ready for protein synthesis, while uncharged tRNA does not have an amino acid attached. Charged tRNA binds to the appropriate codon on the mRNA during translation, while uncharged tRNA cannot participate in translation.
What does tRNA bring amino acid to the nucleus or ribosomes?
tRNA brings the complementary base pair to the mRNA already in place. The complementary base pair codes for a certain amino acid. So tRNA does bring the amino acids to the ribosome by bringing the correct code in the sequence to make a protein.
How many amino acids does a single tRNA has?
A single tRNA captures a single type of amino acid.
