Protozoa and Other Protists
synkaryon, rapid replication of chromosomes occurs and the macronucleus
becomes polyploid, with in some cases a stage when polytene chromosomes are
visible. In the fully formed macronucleus the chromatin is confined to many small

Introduction to Animal Cytogenetics
THE PROTOZOAN MACRONUCLEUS Ciliated protozoa, amongst which the
most familiar organisms are probably Paramoecium and Tetrahymena, are
characterized by having two kinds of nucleus, a micronucleus and a
macronucleus.

Molecular Biology of RNA
Tetrahymena cells are somewhat unusual amongst eukaryotes because they
contain two nuclei: a transcriptionally inactive diploid micronucleus and a
transcriptionally active polyploid macronucleus. A picture of a Tetrahymena cell
containing ...

Transgenerational Epigenetics
These remaining scnRNAs are shuttled back to the developing macronucleus,
where they recruit chromatin proteins to homologous sequences (the IESs) and
coordinate their elimination from the new macronucleus. DNA elimination by this
...
On the other hand, the macronucleus is indispensable for the occurrence of
autogamy, since cells lacking it are unable to undergo meiosis even if the
micronuclei are present (SONNI BORN & SCHNELLI R 1955). The microinjection
technique ...
In both cases they observed that the corresponding genes are deleted from the
new macronucleus. In other words, dsRNA that enters the new macronucleus is “
interpreted” by the new macronucleus as a sequence that was made in the ...

International Review Of Cytology: A Survey of Cell Biology
While the micronucleus contains no nucleoli, numerous nucleolus‐like structures
are seen in the macronucleus, although they seem to diVer in structure from
typical nucleoli (Postberg et al., 2005). In both nuclei the DNA is organized into ...
