Ribosomes are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains. Ribosomes consist of two major … Visa mer The sequence of DNA that encodes the sequence of the amino acids in a protein is transcribed into a messenger RNA chain. Ribosomes bind to messenger RNAs and use their sequences for determining the correct sequence of … Visa mer The ribosome is a complex cellular machine.

The ribosomal proteins and rRNAs are … Visa mer Ribosomes are classified as being either "free" or "membrane-bound". Free and membrane-bound ribosomes differ only in their spatial distribution; they are identical in … Visa mer The ribosome may have first originated as a protoribosome, possibly containing a peptidyl transferase centre (PTC), in an RNA world, appearing as a self-replicating complex that only later evolved the ability to synthesize proteins when amino acids began to appear. … Visa mer Ribosomes were first observed in the mid-1950s by Romanian-American cell biologist George Emil Palade, using an electron microscope, as dense particles or granules. They were … Visa mer Ribosomes are minute particles consisting of RNA and associated proteins that function to synthesize proteins. Proteins are needed for many cellular functions such as repairing … Visa mer In bacterial cells, ribosomes are synthesized in the cytoplasm through the transcription of multiple ribosome gene operons.
