Cell division is the mechanism by which DNA is passed from one generation of cells to the next and ultimately, from parent organisms to their offspring. Although eukaryotes and prokaryotes both engage ...

The chromatids arrive at the either end of each cell and new nuclear membranes form. With meiosis in a female, there is only one dividing cell at this point. As in telophase I, the cytoplasm of the ...

FROM observations made in this laboratory by S. G. Smith, E. Marie Hearne, Jane D. Spier, J. M. Armstrong, A. W. S. Hunter, and me on meiosis and both haploid and diploid mitosis in Trillium, ...

Researchers are examining how the processes that regulate gene expression and chromosome behaviors can lead to health issues, including cancer, birth defects, miscarriage, and infertility. Researchers ...

Interphase is the period between cell divisions. During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating bases attach to the unzipped strands. The ...
