Human chromosomes, SEM C013 / 5005
Human chromosomes. Coloured scanning electron micrograph (SEM) of human chromosomes prepared with the harlequin staining technique. Chromosomes are a packaged form of a cells genetic material DNA (deoxyribonucleic acid). The DNA condenses into chromosomes during cell replication. Each chromosome consists of two identical strands (chromatids), aligned parallel to each other and joined at an area called the centromere. The staining shows the formation sequence, with the second chromatid (yellow) of each pair formed as a direct copy of the first chromatid (purple). Structural changes are also seen

EDITORS COMMENTS
This print showcases the intricate beauty of human chromosomes, captured using a scanning electron microscope (SEM) and prepared with the harlequin staining technique. The image reveals the packaged form of a cell's genetic material, DNA, which condenses into chromosomes during cell replication. Each chromosome consists of two identical strands called chromatids, aligned parallel to each other and joined at an area known as the centromere. The stunning false coloration highlights the formation sequence, with the second chromatid (yellow) in each pair formed as a direct copy of the first chromatid (purple). Additionally, structural changes within these chromosomes are also visible. The black background enhances the vibrant colors and emphasizes their significance in cellular biology. This mesmerizing image not only represents our genetic makeup but also symbolizes health and normality within our biological systems. With its detailed portrayal of chromosomal structures and genetic material organization, this photograph serves as a valuable resource for researchers studying genetics and cell biology. It offers insights into how DNA is condensed into chromosomes while showcasing various aspects such as staining techniques used to visualize these microscopic structures. Captured by SCIENCE PHOTO LIBRARY using advanced SEM technology, this print provides an awe-inspiring glimpse into one of nature's most fundamental building blocks – human chromosomes.
