Electrophoresis Equipment. Electrophoresis equipment applies an electric charge to molecules, causing them to migrate towards their oppositely charged electrode. The technique is found in all research and clinical laboratories utilizing DNA and protein applications, and is divided into gel and capillary techniques.lectrophoresis Equipment.

primary spermatocyte a diploid cell that has derived from a spermatogonium and can subsequently begin meiosis and divide into two haploid secondary spermatocytes. secondary spermatocyte one of the two haploid cells into which a primary spermatocyte divides, and which in turn gives origin to spermatids.
Primary oocyte. Definition. noun, plural: primary oocytes. The oocyte that arises from the oogonium via the process of oocytogenesis, and gives rise to secondary oocyte and polar body after first meiotic division (meiosis I).Supplement. In humans, the primary oocytes are produced by the process of oocytogenesis that occurs during embryonic stage.At that time each oogonium inside the ovaries of the fetus divides and enters the initial stage of meiosis I to become the primary oocyte.upplement.
