Cytokinesis
Cytokinesis. Fluorescent micrograph of an animal cell during cytokinesis (cell division). Cytokinesis occurs after nuclear division (mitosis), which produces two daughter nuclei, containing deoxyribonucleic acid (DNA, white). A contractile ring made of actin filaments (red) forms beneath the cells plasma membrane. This ring contracts, creating a furrow in the cytoplasm. The furrow deepens, separating the cytoplasm and cell organelles, until the two new cells are formed. The blue structures are microtubules, part of the cells cytoskeleton, they separate the chromosomes during mitosis

EDITORS COMMENTS
This print showcases the intricate process of cytokinesis, capturing a fluorescent micrograph of an animal cell during cell division. The image depicts the crucial stage following nuclear division, where two daughter nuclei containing DNA (depicted in white) have been formed. At this point, a contractile ring composed of actin filaments (shown in red) emerges beneath the cells' plasma membrane. As the contractile ring contracts, it creates a furrow within the cytoplasm. This furrow gradually deepens and separates the cytoplasm along with its organelles until two distinct new cells are ultimately produced. The blue structures visible in the image are microtubules, which play a vital role in segregating chromosomes during mitosis. The photograph not only highlights the complexity and precision involved in cellular processes but also emphasizes their significance for biological functions. It offers viewers a glimpse into the microscopic world that underlies life itself. Captured by Science Photo Library, this stunning visual representation provides valuable insights into cytology and genetics while showcasing cutting-edge fluorescence microscopy techniques such as wide field deconvolution. Its vibrant colors and detailed composition make it an ideal addition to any scientific collection or educational resource related to cell biology or genetic research.
