Answer:
Ribosomes are organelles that participate in protein synthesis.
Step-by-step explanation:
For individual ribosomes to participate, they must be interconnected. Thus, ribosomes become active in protein synthesis only when they come into contact with mRNA.
Several individual free ribosomes bind to the mRNA that passes between their subunits and therefore forms a structure called polysome, which resembles a low bead.
The number of ribosomes in the polyribosome is determined by the complexity of the protein it synthesizes, ie the number of amino acids in the protein. Thus, for example, hemoglobin is composed of 150 amino acids, and the polysomes that synthesize this protein consist of only 5 ribosomes.
