Chromosomes, SEM
Chromosomes. Coloured scanning electron micrograph (SEM) of two chromosomes. The SEM is overlaid on a DNA autoradiogram background. Chromosomes contain the genetic material DNA (deoxyribonucleic acid). These chromosomes are at a stage where they have replicated. The replicate (copy) and the original are termed chromatids and align parallel to each other, joined at an area called a centromere. The 46 human chromosomes hold the DNA that carries the genetic code, unique for every individual. DNA controls the development and functioning of every living organism. The code consists of the sequence of DNA nucleotide bases, seen as the bands (black) on an autoradiogram. Magnification unknown

EDITORS COMMENTS
This print showcases the intricate beauty of chromosomes, as seen through a coloured scanning electron micrograph (SEM). The image is overlaid on a DNA autoradiogram background, adding depth and complexity to the visual composition. Chromosomes are fundamental components of our genetic makeup, containing the vital material known as DNA (deoxyribonucleic acid). In this particular snapshot, we witness two replicated chromosomes at an advanced stage. The original chromosome and its copy, called chromatids, align parallel to each other and are joined by a centromere. Within these 46 human chromosomes lies the unique genetic code that defines every individual. This code controls the development and functioning of all living organisms. It consists of a sequence of nucleotide bases found in DNA, which can be observed as distinct black bands on the autoradiogram. The magnification used for this SEM image remains unknown but reveals astonishing details that would otherwise remain hidden from our naked eye. Through careful analysis and sequencing techniques, scientists unravel patterns within these lines and bases to unlock invaluable insights into genetics. This mesmerizing print serves as a testament to both the complexity and elegance inherent in biological systems while reminding us of the profound impact that DNA has on shaping life itself.
