Question

Which of the prokaryotic subunits are involved in translocation, in which mRNA moves through the ribosome.... 50S, 30S, or both?

Answer 1

Both the 30S and 50S subunits of the ribosome are involved in translocation in prokaryotes.

Step-by-step explanation:

In prokaryotic cells, both the 30S and 50S subunits of the ribosome are involved in translocation. The mRNA moves through the ribosome with the help of these two subunits. The small 30S subunit is responsible for binding the mRNA template, while the large 50S subunit sequentially binds tRNAs.
