The connection of the aminoacids with tRNA is one of the most important steps leadind to the protein syntesis. It happens with the help of an enzyme complex named aminoacyl-tRNA syntetase, which is specific for each of the twenty aminoacids, that is able to recognize the specific tRNA based on sequence match of the anticodon.

How many different aminoacyl trna synthetases are there?
20
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.
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.
Translation begins when the initiator tRNA binds to the?
Initiation involves binding of mRNA and initiator aminoacyl-tRNA to small subunit, followed by binding of large subunit. Initiation codon in mRNA (AUG)
How does amino acids get to the site of protein synthesis?
Amino acids are attached to transfer RNA to form an aminoacyl-tRNA and diffuse to the ribosome, which is the site of protein synthesis.
How many different aminoacyl trna synthetases are there?

What are the reactions required to generate an aminoacyl tRNA?
The overall reaction commonly proceeds in two steps: (i) formation of an aminoacyl-adenylate and (ii) transfer of the activated amino acid moiety of the mixed anhydride to either the 2'-OH (class I aminoacyl-tRNA synthestases) or 3'-OH (class II aminoacyl-tRNA synthestases) of the ribose of the terminal adenylic acid at the 3'-CCA terminus common to all tRNAs.
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.
Does tRNA deliver amino acids to ribosome?
n aminoacyl tRNA synthetase (aaRS) is an enzyme that catalyzes the esterification of a specific amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA (wikipedia)
Amino acid binds to which part of the trna?
carboxyl group of an amino acidf.franklin.....
How does aminoacyl-tRNA synthesis work?
The DNA from the nucleus is read in the ribosomes, which makes proteins. Then the protein is "perfected" in the endoplasmic reticulm, put in a vesicle and sent to the Golgi apparatus where it is package in a vesicle once more and sent out into the cell were it becomes part of the membrane, the cytoplasm, or the lysosomes.
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.
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 part of the cell does tRNA come from?
tRNA comes from aminoacyl-tRNA synthetases. An Amino Acid, Nucleotide, and Anticodon are bound together by an enzyme. It is then used for protein synthesis. Source: I am in a college level Biology class.
What is an aminoacylation?
An aminoacylation is an addition of an aminoacyl group to a compound, especially as a part of the process of synthesizing proteins via aminoacyl tRNA synthetase.
What is the name of the enzyme that causes the formation of the peptide bonds between amino acids during translation of protein synthesis?
aminoacyl-tRNA synthetase
Translation begins when the initiator tRNA binds to the?
Initiation involves binding of mRNA and initiator aminoacyl-tRNA to small subunit, followed by binding of large subunit. Initiation codon in mRNA (AUG)
