Artwork of human motor neuron (nerve cell)

Motor neuron. Illustration of a human motor neuron (nerve cell). The arrows show the direction of the nervous impulse, which enters the cell body (top left) through minute processes called dendrites. The impulse is then transmitted along the axon, which may be several metres long, at up to 430km per hour. The axon is enclosed in a myelin sheath (red) produced by Schwann cells (brown, nuclei represented by bulges). At the end of the axon the signal is transmitted to an effector organ, such as a muscle

Computer artwork of part of a beta DNA molecule

DNA molecule. Computer representation of a segment of the molecule Deoxyribonucleic Acid (DNA). This structure contains all the inherited instructions necessary for the development of a living organ- ism. Here, colour-coded ribbons and bars depict the structure of the molecule. DNA is composed of two strands twisted into a helical shape, each strand consisting of an outer sugar-phosphate backbone (pink, red). Projecting inward from this backbone are bases (multicoloured) which pair up in a complementary fashion to form a code of instructions. Sixteen base pair units are repre- sented here. Genetic information is determined by the arrangement of base pairs along the molecule
