Magnesium

Vedclass · Answer

(B) Magnesium $(Mg^{2+})$ ions play a crucial role in the structural stability of ribosomes. Ribosomes are composed of two subunits,a larger subunit and a smaller subunit. Magnesium ions help in maintaining the association of these two subunits by binding to the ribosomal $RNA$ $(rRNA)$ molecules. Without sufficient $Mg^{2+}$ concentration,the ribosomal subunits tend to dissociate,rendering the ribosome inactive for protein synthesis.
