Complete the following vocabulary exercise related to the process of translation of mRNA to protein by the ribosome.
Deffense [45]

When mRNA exits the nucleus, it travels to a ribosome, which is made up of proteins and rRNA. The ribosome reads the mRNA's codon sequence. The correct sequence of amino acids is delivered to the ribosome by tRNA molecules. A ribosome is responsible for translating the codons in mRNA into a chain of amino acids.

Initiation, elongation, and termination are the three main stages of translation. The small subunit and the big subunit are two distinct subunits that make up the ribosome. The tiny subunit binds to the mRNA's 5' end during initiation.

Then it shifts in a 5' x 3' direction. The TR when RNA that has an amino acid linked to it binds to the mRNA. They participate in translation because they are molecules that are involved in protein synthesis, which is translation. And those molecules that link the minor assets Holden's RNA from M. with. The mRNA is now bound to the tRNA by antipodean.
