Amino acids are assembled into a protein on the ribosome

Ribosomal RNA and transfer RNA form base pairs

|
|
Messenger RNA is made from DNA
|
|
|
Transfer RNA contains the genetic code copied from DNA
|
Explanation:
Detailed explanation-1: -During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.
Detailed explanation-2: -The tRNA brings these amino acids, protein’s building blocks, to the ribosome. Each tRNA molecule has two distinct ends or sites, one to bind a specific amino acid, and another to bind the corresponding mRNA codon.
Detailed explanation-3: -tRNA carries and transfers an amino acid to the polypeptide chain being assembled during translation.
