Science / Biology / Ribosomes: Small organelles made of rRNA and protein in the cytoplasm of prokaryotic and eukaryotic cells; aid in the production of proteins on the rough endoplasmic reticulum and ribosome complexes. The site of protein synthesis. The ribosome is composed of two subunits that attach to the mRNA at the beginning of protein synthesis and detach when the polypeptide has been translated.
Science / Genetics / Transfer RNA (TRNA): A class of rna having structures with triplet nucleotide sequences that are complementary to the triplet nucleotide coding sequences of mrna. The role of trnas in protein synthesis is to bond with ami MORE
Science / Genetics / Ribosomal RNA (RMA): A class of rna found in the ribosomes of cells. MORE
