why is tRNA called adapter molecule???

An adapter is a device that acts as a mediator between two systems that are not compatible similarly tRNA acts as an adpater which mediates the conversion of sequence of Nucleotides (mRNA) into sequence of amino acids (proteins).

Because Crick believed that there must be an adapter molecule capable of mediating the translation of the RNA alphabet into the protein alphabet...that ended up being tRNA

 tRNA is called adapter molecule because in one hand it reads the codes on mRNA and on the other hand it binds with specific amino acids.

hope this wil help u!
