Example Sentences

This hypothesis is consistent with the finding that lagging chromosomes during anaphase can become sequestered in micronuclei and subjected to chromosomal pulverisation before rejoining the main nucleus.

From Nature

The metaphase is the parting of the sister chromosomes in the equatorial plate; their passage to opposite poles of the spindle constitutes the anaphase; and their reconstruction to form the resting daughter nuclei, the telophase.

From Project Gutenberg

An early anaphase of this mitosis is shown in figure 19; here the small chromosome is already divided.

From Project Gutenberg

In the anaphase the chromosomes are often split as in figure 68, and occasionally the two components can be seen as plainly as in figure 65.

From Project Gutenberg

The first division is thus a reducing division, while the split appearing in the anaphase of the heterotype and presumably reappearing in the prophase of the homotype is the original split of the spireme thread.
