‘Thus transcribing RNA polymerases and ribosomes may all be bound to the same RNA molecule while marching in the same direction.’ ‘This necessitated a mechanism for the import of the now nucleus-encoded proteins, which are synthesized at free ribosomes in the cytoplasm.’

ribosomes definition: Noun 1. plural form of ribosome... Ribosomes are vital to the survival of any organism.; Ribosomes are known as the "protein factories" of the cell.
The ribosome is a large complex molecule which is responsible for catalyzing the formation of proteins from individual amino acids using messenger RNA as a template.  This process is known as translation.Ribosomes are found in all living cells. The sequence of DNA encoding for a protein may be copied many times into messenger RNA (mRNA) chains of a similar sequence.
Definition of Ribosome. The ribosome is a complex molecular machine found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.
ribosome: 1 n any of a group of particles in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for use by the cell “the ribosome is the site of protein ...
What is the definition of Ribosomes? Give at least 4 examples, and facts/characteristics. Cellular Organelles. The cell contains many organelles that perform specialized functions for the cell ...
Ribosomes: Definition, Structure, and Functions. What are Ribosomes. Ribosomes are cell structures present in large numbers in all living cells acting as the site of protein synthesis. In prokaryotes, they float freely in the cytoplasm, while in eukaryotes they are free or remain bound to the outer membrane of the endoplasmic reticulum.
Ribosomes Definition The ribosome word is derived – ‘ribo’ from ribonucleic acid and ‘somes’ from the Greek word ‘soma’ which means ‘body’. Ribosomes are tiny spheroidal dense particles (of 150 to 200 A 0 diameters) that are primarily found in most prokaryotic and eukaryotic.
The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). The morphological distinction between the two is the presence of protein-synthesizing particles, called ribosomes, attached to the outer surface of the RER.The functions of the SER, a meshwork of fine tubular membrane vesicles, vary considerably from cell to ...
