Fill in the fоllоwing pаrаgrаph abоut the genetic code using the provided word bank. Translation is the process in which a protein is produced from the code of a/an _______ molecule. In the initiation of translation, the initiation complex forms, which contains, the ribosome, mRNA, and a/an _______ molecule attached to an amino acid. The next amino acid is brought in by a tRNA, whose _______ sequence compliments the mRNA codon sequence. A catalytic RNA in the ribosome called a _______ catalyzes the reaction that binds the amino acids together. The ribosome then shifts one position in a process called _______ The elongation process continues until the ribosome reaches a codon that signals the termination of translation called the _______ codon.
