F / col TEM of polyribosomes from brain cell
False-colour transmission electron micrograph (TEM) of a polyribosome from a human brain cell. Polyribosomes (or polysomes) are beads of individual ribosomes connected by slender strands of messenger RNA (mRNA), one of the three types of ribonucleic acid. They exist as sites of protein synthesis within a cell. In this cell, a neurone, protein is required for internal use in an extensive cytoplasm. mRNAs role is in carrying genetic information from the nucleus to the ribosomes to be translated into an amino acid sequence of specific proteins. Magnification: x240, 000 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate world of polyribosomes within a human brain cell. In this false-color transmission electron micrograph (TEM), we are granted a glimpse into the fascinating process of protein synthesis taking place within our very own minds. Polyribosomes, also known as polysomes, are clusters of individual ribosomes linked together by delicate strands of messenger RNA (mRNA). These beads-like structures play a crucial role in the creation of proteins inside cells. Within this particular neuron, proteins are essential for internal use within its extensive cytoplasm. The mRNA's primary function is to transport genetic information from the nucleus to the ribosomes, where it is translated into specific amino acid sequences that form vital proteins. This complex interplay between genetics and cellular machinery ensures proper functioning and communication within our brains. At an astonishing magnification level of x240,000 on a 6x7cm size scale, this image offers us an up-close view into the hidden intricacies that make up our neural networks. It serves as a reminder of both the beauty and complexity found within every single brain cell. Science Photo Library has once again captured an awe-inspiring moment in scientific exploration with their impeccable photography skills. This print not only provides valuable insights into biochemistry and genetics but also sparks wonder about the wonders unfolding inside each one of us.
