Answer :

In any given species, there are at least 20 types of aminoacyl trna synthetases

The required details about Aminoacyl-tRNA is mentioned in below paragraph.

Aminoacyl-tRNA, commonly known as aa-tRNA or charged tRNA, is a kind of tRNA that has a chemical connection with its corresponding amino acid (charged). The amino acid is delivered to the ribosome via the aa-tRNA and certain elongation factors to be incorporated into the polypeptide chain that is being created during translation. The substrate required to enable the synthetases of peptide bonds inside a developing polypeptide chain is not an amino acid by itself. In order to create their corresponding aa-tRNA, amino acids must first be "charged" or aminoacylated with a tRNA.

Every amino acid has a unique aminoacyl-tRNA synthetase that is used to chemically bond to the tRNA to which it is specific, or, to use another term, "cognate" to.
