Question

What type of RNA acts like a delivery truck, delivers amino acids to the ribosome for protein synthesis, and then leaves empty again, to go collect another amino acid?

Answer 1

The correct answer is this one: "Transfer RNA." The type of RNA that acts like a delivery truck, delivers amino acids to the ribosome for protein synthesis, and then leaves empty again, to go collect another amino acid is called the Transfer RNA.

Answer 2

The correct answer is Transfer of RNA.

Transfer of RNA acts as the delivery truck which delivers amino acid to the ribosome for the synthesis of protein and then leaves empty again. Transfer RNA is termed as an adaptor molecule which is composed of RNA which have 76-90 number of nucleotides in length.
It is a link which is between amino acids sequence and mRNA of proteins. The work of tRNA is to specify which sequence from genetic code corresponds to amino acids. mRNA encodes the protein as series of contiguous codons. Its structure can be decomposed into a primary and secondary structure.
