Chromosome, SEM
Chromosome. Coloured scanning electron micrograph (SEM) of a condensed chromosome showing chromomeres. Chromosomes, which consist of two identical chromatids joined at a centromere, are comprised of deoxyribonucleic acid (DNA) coiled around proteins. This complex is known as chromatin. Chromomeres are granules of concentrated chromatin that show as transverse bands on the chromosomes. DNA contains sections, called genes, which encode the bodys genetic information, determining each cells structure, function and behaviour. Magnification: x12, 400 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a condensed chromosome, as seen through a coloured scanning electron microscope (SEM). The chromosomes, composed of DNA coiled around proteins known as chromatin, are essential carriers of genetic information. In this image, we can observe the presence of chromomeres - granules of concentrated chromatin that appear as transverse bands on the chromosome. DNA, the building block of life, contains genes that encode vital information determining the structure, function, and behavior of every cell in our body. This genetic material is inherited and plays a crucial role in heredity and genome regulation. The level of detail captured by SEM technology is truly remarkable; with a magnification factor exceeding 12,400 times when printed at 10 centimeters wide. The false coloration applied to this image enhances its visual impact while maintaining scientific accuracy. This photograph not only highlights the complexity and elegance inherent in biological systems but also serves as a reminder of humanity's ongoing quest to unravel the mysteries encoded within our own DNA. It represents an invaluable resource for researchers studying genetics, genomics, and other fields related to human health and well-being.
