RM2BE0GP8–Transmission electron micrograph (TEM) of plasmids. Plasmids are symbiotic pieces of DNA (deoxyribonucleic acid) that occur in bacteria and yeast. They are separate from the main chromosome, replicate independently, and can be transferred from one cell to another carrying genes with them. This property of plasmids is exploited in genetic engineering, and is one of the ways in which resistance to antibiotics spreads among bacteria. Magnification unknown.

RM2BE0H0R–Light micrograph showing mitosis in whitefish blastula, early telophase. No magnification given. Mitosis, the usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell. The four main phases of mitosis are prophase, metaphase, anaphase, and telophase. Blastula, an animal embryo at the stage immediately following the division of the fertili

The chromatin segments arrange them-selves along the equatorial line of the spindle. The nuclear membrane and nucleolus disappear during thisphase. The Metaphase, in which actual division of the nucleus occurs. Each chromosome (or segment of chromatin) splits longi-tudinally, forming daughter chromosomes. The Anaphase, in which the changes are in the main the re-verse of those occurring in the prophase. The daughter chromosomes separate,

My own figures occasionally show a double chromosome at one pole in advance of the main complex, and the evidence favors Guyer's interpretation rather than Gutherz's, but there is here nothing so striking as one sees in certain insects (e. g., the phasmid, Aplopus mayeri) and the opossum. Strong evidence for the presence of a heterochromosome in man is given by Gutherz in his illustrations of ear
