The structure that reads RNA and links amino acids together to make proteins is called a ribosome.

Here's a breakdown:

* Ribosomes are complex molecular machines found within cells.

* They are composed of ribosomal RNA (rRNA) and proteins.

* mRNA (messenger RNA), carrying the genetic code from DNA, binds to the ribosome.

* The ribosome reads the mRNA codons (three-nucleotide sequences) and matches them with corresponding tRNA (transfer RNA) molecules.

* Each tRNA carries a specific amino acid.

* The ribosome links the amino acids together in a chain, following the sequence dictated by the mRNA, forming a polypeptide chain.

* The polypeptide chain folds into a specific three-dimensional structure, creating a functional protein.

So, the ribosome is the essential machinery that translates the genetic information in RNA into the building blocks of life – proteins.
