Which type of RNA has an amino acid acceptor end to which it binds to amino acids ?

tRNA

The correct answer is Option (3) - tRNA

The type of RNA that has an amino acid acceptor end to which it binds to amino acids is transfer RNA (tRNA).

Transfer RNA (tRNA) is a type of RNA molecule that plays a critical role in protein synthesis (translation) within cells. Each tRNA molecule carries a specific amino acid at one end and has an anticodon sequence at the other end, which pairs with the corresponding codon on the mRNA during protein synthesis.

The amino acid acceptor end of the tRNA molecule binds to and carries a specific amino acid, ensuring that the correct amino acid is delivered to the ribosome based on the codons on the mRNA strand. This process allows for the accurate incorporation of amino acids into the growing polypeptide chain during protein synthesis.

Therefore, among the options provided, it is the tRNA that has an amino acid acceptor end to which it binds to amino acids.
