The normally 'condensed' (darkly stained) chromosomes of dinoflagellates decondense by swelling. This occurs in an increasing number of cells when the concentration of added OsO4 is decreased. With different fixatives other types of disintegration ca

Unfixed and glutaraldehyde-fixed spinach chloroplasts were frozen on a copper block cooled by liquid helium and subsequently substituted in acetone at −87°C. Fixed chloroplasts were substituted in pure acetone, unfixed ones also in acetone contain

F-plasmid-mediated bacterial conjugation was studied with hfr (traDts) and tra I mutant Escherichia coli donor strains. This allowed us to observe a statistically significant number of conjugation-specific contacts by video and electron microscopy. S

A new procedure of immunostaining sections of cryofixed and freeze-substituted Escherichia coli shows that DNA extends from its bulk into small ribosome-free spaces throughout the cytoplasm, resulting in a coralline-shaped nucleoid. Low-resolution im

Sulfolobus acidocaldarius and Thermoplasma acidophilum prefer extreme living conditions of low pH (60°C) for optimal growth. To resist thermal denaturation of DNA it appears to be associated with helix stabilizing proteins.The chromosomal position o
