LM of Drosophila giant (polytene) chromosome
Giant chromosome. Coloured computer-enhanced light micrograph of a giant (polytene) chromosome in a salivary gland cell of the fruit fly Drosophila funebris. Chromosomes are the thread- like structures present in the nucleus of all plant and animal cells. They contain the sequences of genes which govern inherited characteristics. The giant chromosome of the fruit fly is enlarged by repeated replica- tions (polyteny). A clear pattern of transverse bands (red & black) called chromomeres can be seen. Particular patterns help identify different parts of chromosomes and in the mapping of genes. Magnification: x390 at 5x7cm size. x985 at 18x10.5cm

EDITORS COMMENTS
This print showcases the intricate beauty of a Drosophila giant (polytene) chromosome, providing a glimpse into the fascinating world of genetics. The image, captured using computer-enhanced light micrography, reveals a stunningly detailed view of this enlarged chromosome found in a salivary gland cell of the fruit fly Drosophila funebris. Chromosomes, depicted as thread-like structures within plant and animal cells' nuclei, play a crucial role in determining inherited characteristics through their gene sequences. In this particular case, the giant chromosome is magnified due to repeated replications known as polyteny. Its distinct transverse bands colored in red and black are called chromomeres and serve as vital markers for identifying different parts of chromosomes and mapping genes. The sheer complexity and precision visible in this photograph highlight both the elegance and intricacy present within nature's blueprint for life. With magnification levels reaching x390 at 5x7cm size or an astounding x985 at 18x10.5cm size, every minute detail becomes apparent to those who observe it closely. This mesmerizing image from Science Photo Library not only offers scientific insight but also serves as a testament to the wonders that can be uncovered when artistry meets technology in capturing nature's most extraordinary creations.
