Which of the following elements helps in maintaining the structure of ribosomes?

Step-by-step solution

Each ribosome is made up of two subunits - a large and a small subunit. A 70S ribosome is made up of 50S, large subunit and 30S, small subunit. An 80S ribosome is made up of 60S, large subunit and 40S, small subunit. 0.001 M Mg +2 concentration is required for the association of two subunits. As a result, the intact ribosome is formed.
