In the choreography of meiosis—the process responsible for sex cell division in all eukaryotic life—the pairing of homologous chromosomes (homologs) is essential. Errors in this process can lead to an ...

As in prophase I, the chromosomes condense, spindles form, the centrioles begin to separate, and the nuclear membrane fragments and disperses. Unlike prophase I, the chromosomes do not attach to the ...

Cell division allows a single fertilized egg to develop into a living being, our skin to renew itself, and wounds to heal. Before each cell division, termed mitosis, the genetic information must first ...

A computer simulation shows the two step process for a condensing chromosome, which happens as the cell moves from interphase to metaphase. In the first phase, chromatin loops of 80,000 to 120,000 DNA ...

Download the latest edition Their analysis showed that the molecular density surrounding chromosomes increased with the progression from the prophase to anaphase stages of mitosis, concurring with ...

The process of cell division, or mitosis, has fascinated biologists since its discovery in the late 1870s. Progress through mitosis is traditionally divided into stages that were defined over 100 ...
