Ribosomal RNA<span> (rRNA) associates </span>with<span> a set of </span>proteins<span> to form ribosomes. These complex structures, which physically move along an mRNA </span>molecule<span>, catalyze the assembly of amino acids into </span>protein<span> chains. They also bind tRNAs and various accessory </span>molecules<span> necessary for </span>protein<span> synthesis.</span>
Protein building begins with the DNA strand in the Ribosome. The DNA strand is essential to dictating the type of protein that is to be produced, based on the sequence of nucleic acids.
<span>This result is produced by the selective permeability of the plasma membrane when the presence of negatively charged ions does not diffuse into the cell and the action of several sodium-potassium pump units causes an unequal distribution of charges through the membrane.</span>
<span> Inside its enclosed nuclear membrane, it contains the majority of the cell's genetic material which this material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.</span>
