Male sex chromosomes, SEM
Male sex chromosomes. Coloured scanning electron micrograph (SEM) of human X (centre) and Y (upper left) sex chromosomes. Each chromosome has replic- ated to form two identical strands (chromatids). The area linking the chromatids is the centromere. The sex chromosomes inherited during fertilisation determine a persons gender. Males have an X and a Y chromosome (as seen here), whilst females have two copies of the X chromosome. The Y chromosome carries instructions for the development of male characteristics. The sex chromosomes are one pair of 23 pairs present in most cells in the body, which contain the DNA necessary for growth and development. Magnification: x7150 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate details of male sex chromosomes, captured through a coloured scanning electron micrograph (SEM). In the image, we can observe two identical strands, known as chromatids, which have replicated from a single chromosome. The centromere serves as the connecting link between these chromatids. These sex chromosomes play a crucial role in determining an individual's gender during fertilization. Males possess both an X and Y chromosome, while females carry two copies of the X chromosome. It is on the Y chromosome where instructions for developing masculine characteristics are encoded. Within most cells of our body, there exist 23 pairs of chromosomes that contain DNA essential for growth and development. This particular SEM magnification allows us to explore this genetic blueprint at x7150 scale when printed at 6x7cm size. The image not only highlights the biological aspects but also emphasizes the significance of genetics in shaping our identities. As we delve into this microscopic world, it becomes evident how cell division and replication contribute to maintaining our unique traits encoded within each double helix structure. Science Photo Library has once again provided us with an awe-inspiring glimpse into the wonders of biology and anatomy through their exceptional collection capturing nature's hidden beauty at its finest.
