The membrane component of the ribosomal bodies from the lizardLacerta sicula: a freeze-etching study
- 8 Downloads
We have studied, using the freeze-etching technique, the cytomembranes of the flat cystenae, regularly interposed between the cristalline sheets of ribosomes, inside the ribosomal bodies of the hibernating lizardLacerta sicula. The results show the presence, on the protoplasmic face (PF), of numerous IMPs (intramembrane particles) which can be separated into two populations. The flatter ones appear to be arranged in a regular pattern, with the support of the optical diffraction analysis, can be correlated with the disposition of the ribosomes in the cristalline sheets.
