The Distribution of Dna among Dividing Mitochondria of Tetrahymena Pyriformis
A squash technique was developed for log phase Tetrahymena pyriformis which permitted the resolution of over 100 individual mitochondria from a single cell. Mitochondria incorporated thymidine at all stages of the cell cycle, even when nuclear DNA synthesis was not occurring. During the stage of macronuclear DNA synthesis, however, there was a significant increase in the extent of mitochondrial...
متن کاملThe Fate of Mitochondria during Aging in Tetrahymena Pyriformis
During the growth cycle of Tetrahymena pyriformis the mitochondria undergo changes in position, number, and structure. Ciliates in the logarithmic growth phase possess elongated mitochondria which are aligned along the plasma membrane and are closely associated with the kinetosomes and kinetodesmata. Mitochondria appear to divide across the long axis at this time, resulting in two or more produ...
متن کاملMicrotubules from the Cilia of Tetrahymena Pyriformis
Frayed cilia from Tetrahymena pyriformis have been examined in the electron microscope using both uranyl acetate and phosphotungstic acid as negative stains. Observations on the central microtubules show that one member of the pair exhibits two rows of short projections. These are about 18 nm long, and are spaced longitudinally at 16-nm intervals. In many specimens the projections are separated...
متن کاملReactivation of Glycerinated Cilia from Tetrahymena Pyriformis
The ease with which Tetrahymena can be grown in relatively large quantity makes it an exceptionally useful source of cilia for biochemical study. Several methods of isolating the cilia have been described (3, 11). Although excellent for many purposes, these procedures all suffer from the limitation that the isolated cilia seem incapable of being reactivated by ATP. This paper describes a method...
متن کاملMitochondrial and Cytoplasmic Ribosomes from Tetrahymena Pyriformis
Mitochondrial and cytoplasmic ribosomes from Tetrahymena pyriformis have been isolated and studied by the techniques of polyacrylamide gel electrophoresis and electron microscopy used in conjunction. Although the two ribosome types show the same coefficient of sedimentation (80S) in sucrose gradients, they can be distinguished by gel electrophoresis: mitoribosomes migrate in a single band, cons...
