Ribosomes and dna

WebbA ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward … Webb7 feb. 2024 · Bacterial ribosomes are hulking complexes made of three RNA molecules and more than 50 proteins. Those components are divided between a small and a large subunit, which have separate roles in protein synthesis. In simple terms, the small subunit binds to and decodes the messenger RNA (mRNA), which contains the protein-making instructions.
