Tetrahymena Thermophila
B. Analysis of the Cell Cycle 1. Associations of Cortical and Nuclear Events How
is the cortical cycle integrated with the nuclear cycles? I will first consider the
association of cortical development with macronuclear DNA synthesis, then with
...

International Review Of Cytology: A Survey of Cell Biology
distribution of DNA to the two daughter macronuclei is often very unequal (Berger
and Schmidt, 1978; Doerder and Debault, 1975), implying that at least at some
stage the two daughter cells contain diVerent numbers of macronuclear DNA ...

hybridization experiments. Using this method, greater than 90% of the
macronuclear DNA molecules were found to contain sequences present in RNA
isolated from whole cells. Thus, the majority of macronuclear DNA molecules are
genes by ...

other hand, ordinary development of macronucleus from the macronuclear
anlage is called NR (nuclear reorganization). The skein formation and
fragmentation of the old macronucleus do not necessarily mean its irreversible
change to ...

In ts401 mutant in autogamous cells the total number of micronuclei and
macronuclear pieces (Table 3) frequently amount to 8. This may signify that
pronuclei without fusion could divide and differentiate in relation to their position
in the cell.

Protozoa and Other Protists
The numerous less-dense nucleoli contain much RNA and many ribosome
components. It has been shown that protein synthesis in the cytoplasm depends
upon RNA of macronuclear origin. Formation of DNA as well as RNA occurs in
most ...

macronucleus in order to interact with the macronuclear chromosome to induce
scnRNA selection (Mid Stage in Fig. 6). The exact molecularmechanism for this
scr1RNA selection process remains unknown; however, two possible

The sequence specificity of the maternal rescue effect was examined using a
genetically wild-type cell line that carried maternally inherited macronuclear
deletions of both the A and B genes (Scott et al., 1994b). These genes are mem-
bers of ...

Handbook of Natural Pesticides
Merozoites with micronuclei apparently continue the cycle of micronuclear
merogony while other microzoites with enlarged, macronuclei apparently begin
macronuclear merogony. Micronuclear meronts and merozoites are the
predominant ...
