The amino acid binding site of tRNA is-A. AnticodonB. DHU armC. 3’ endD. 5’ end [1]

Hint: tRNA is an adaptor molecule made up of RNA that acts as the physical connexion between the mRNA and the protein amino acid chain, usually 76 to 90 nucleotides in length.. At the tip, the anticodon loop has a triplet which pairs the base with the corresponding mRNA codon
Aminoacyl tRNA synthetase (AATS), the enzyme that chemically binds a tRNA to an amino acid via a high-energy bond, recognises the anticodon loop.. Transfer-RNA has post-transcriptionally modified bases of 7-15 percent
It consists of dihydrouracil, an unusual pyrimidine nucleotide stem and loop. In this loop, there are 15-18 nucleotides, with the stem having 3-4 base pairs and the loop having 7-11 unpaired nucleotides.

Aminoacyl-tRNA [2]

Aminoacyl-tRNA (also aa-tRNA or charged tRNA) is tRNA to which its cognate amino acid is chemically bonded (charged). The aa-tRNA, along with particular elongation factors, deliver the amino acid to the ribosome for incorporation into the polypeptide chain that is being produced during translation.
Instead, amino acids must be “charged” or aminoacylated with a tRNA to form their respective aa-tRNA.[1] Every amino acid has its own specific aminoacyl-tRNA synthetase, which is utilized to chemically bind to the tRNA that it is specific to, or in other words, “cognate” to. The pairing of a tRNA with its cognate amino acid is crucial, as it ensures that only the particular amino acid matching the anticodon of the tRNA, and in turn matching the codon of the mRNA, is used during protein synthesis.
Due to the degeneracy of the genetic code, multiple tRNAs will have the same amino acid but different anticodons. Under certain circumstances, non-cognate amino acids will be charged, resulting in mischarged or misaminoacylated tRNA

Site of tRNA that binds to the mRNA molecule is [3]

Right on! Give the BNAT exam to get a 100% scholarship for BYJUS courses. tRNA or transfer RNA is a type of RNA that carries and transfers amino acids to ribosomes during the synthesis of polypeptides in translation
Thus, this process of attachment of an amino acid to the 3’ end of tRNA is called charging of tRNA or aminoacylation of tRNA.. Anticodon loop of tRNA has bases which form hydrogen bonds with the codons on the mRNA

Transfer RNA [4]

Transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA[1]) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes),[2] that serves as the physical link between the mRNA and the amino acid sequence of proteins
Complementation of a 3-nucleotide codon in a messenger RNA (mRNA) by a 3-nucleotide anticodon of the tRNA results in protein synthesis based on the mRNA code. As such, tRNAs are a necessary component of translation, the biological synthesis of new proteins in accordance with the genetic code.
While the specific nucleotide sequence of an mRNA specifies which amino acids are incorporated into the protein product of the gene from which the mRNA is transcribed, the role of tRNA is to specify which sequence from the genetic code corresponds to which amino acid.[4] The mRNA encodes a protein as a series of contiguous codons, each of which is recognized by a particular tRNA. One end of the tRNA matches the genetic code in a three-nucleotide sequence called the anticodon

Transfer RNA [5]

As mentioned earlier, the factory where proteins are manufactured is an organelle called a ribosome. A ribosome is a complicated combination of RNA and other proteins that carries out translation.
A specific and different tRNA molecule exists in the cell for each of the 20 amino acids. The 20 tRNAs are roughly L-shaped molecules with two distinct and widely separated regions.

Chapter 9 � Translation [7]

“The synthesis of every protein molecule in a cell is directed by that cell’s DNA”. Note that there is a direction: the mRNA is read 5’ à 3’.
Please see figures 9-2 and 9-3 for a few more specific details:. The tRNA molecule has several important characteristics:
· Analysis revealed that the genome of this virus was too small to account for all the proteins that it could make.. · The problem was solved by finding that some of fX174’s genes are overlapping:

From RNA to Protein [8]

By agreement with the publisher, this book is accessible by the search feature, but cannot be browsed.. A service of the National Library of Medicine, National Institutes of Health.
However, most genes in a cell produce mRNA molecules that serve as intermediaries on the pathway to proteins. In this section we examine how the cell converts the information carried in an mRNA molecule into a protein molecule
Here was a cryptogram set up by nature that, after more than 3 billion years of evolution, could finally be solved by one of the products of evolution—human beings. And indeed, not only has the code been cracked step by step, but in the year 2000 the elaborate machinery by which cells read this code—the ribosome—was finally revealed in atomic detail.

Transfer RNA (tRNA) “translates” the genetic code into the language of proteins. Each tRNA molecule binds to a specific amino acid on the acceptor arm, recognizes its corresponding code on the mRNA through the anticodon loop region and delivers the amino acid to a growing peptide chain in the ribosome for protein synthesis.
