Lecture № 10-12. STRUCTURE AND FUNCTION of CELLULAR ORGANELLES
Non-membrane organellas of cytoplasm.
Ribosomes, tsentriol; cytoskeleton.
Inclusions.
Ribosomes, tsentriol, microtubules, mikrofilament, intermediate filament belong to not membrane organellas of general purpose.
Ribosomes
Ribosomes (ribosomae) — elementary devices of synthesis of proteinaceous, polypeptide molecules — are found in all cages. Ribosomes — it is difficult ribonukleoproteida which part proteins and molecules of RNA approximately in the equal weight relations are. The size of the functioning ribosome of eukaryotic cells of 25x20x20 nanometers. Such ribosome consists of big and small subjedinitsa. Each of subjedinitsa is constructed of a ribonukleoproteidny tyazh where RRNK interacts with different proteins and forms a ribosome body.
