In exponentially growing Tretrahymena thermophila the DNA content of the following structures was determined by cytophotometry: macronuclei of sister cells immediately after division; micronuclei; extranuclear chromatin in dividing cells and postdividers. Further, the development of macro-nuclear DNA amount in successive cell generations was determined. It was found that chromatin elimination is a frequent process reducing DNA content by about 4% per fission. This chromatin disappears within 20… CONTINUE READING
