Giant chromosomes, SEM P657 / 0034
Giant chromosomes. Coloured scanning electron micrograph (SEM) of giant (polytene) chromosomes from a fruit fly (Drosophila busckii). These chromosomes are formed from repeated rounds of DNA (deoxyribonucleic acid) replication without nuclear division. A process known as endoreduplication. Identical strands sit side by side. The characteristic banding pattern corresponds to areas of high and moderate DNA density. The polytene chromosomes increase cell volume and metabolic rate, as there are more genes to be expressed. The size of the chromosomes also allows for easy study by scientists. Magnification: x575 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of giant chromosomes found in a fruit fly, Drosophila busckii. Through the use of a scanning electron microscope (SEM), this coloured micrograph reveals the remarkable structure and organization of these polytene chromosomes. Formed through multiple rounds of DNA replication without nuclear division, these giant chromosomes exhibit identical strands that sit side by side. The distinct banding pattern observed on the chromosomes corresponds to areas with varying densities of DNA. This unique characteristic allows scientists to study them easily and gain insights into their genetic makeup. The presence of polytene chromosomes in fruit flies serves important biological functions. By increasing cell volume and metabolic rate, they enable more genes to be expressed within each cell. This phenomenon known as endoreduplication contributes to the complexity and functionality of these organisms' genetic material. With a magnification level of x575 when printed at 10 centimetres wide, this image offers a glimpse into the fascinating world of genetics research. It highlights how advancements in technology, such as SEM imaging, have revolutionized our understanding of biology and allowed us to explore even the tiniest details within an animal's body. This mesmerizing photograph is part of Science Photo Library's collection captured by POWER AND SYRED/SCIENCE PHOTO LIBRARY – an invaluable resource for scientific exploration and education alike.
