WebbRNA and protein synthesis review Google Classroom Key terms Structure of RNA DNA alone cannot account for the expression of genes. RNA is needed to help carry out the instructions in DNA. Like DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. WebbRibosomes are non-membranous organelles made of complexes of rRNA and proteins that function as the primary location of protein synthesis. Ribosomes consist of two subunits: the smaller 40S subunit binds and reads the mRNA, and the larger 60S subunit binds the tRNA and amino acids.
