Study of human male meiosis. II-Q-banding in pachytene bivalents. 1978

M L de Torres, and J A Abrisqueta

In continuation of the research on male human meiosis within the study of pachytene bivalents, results from the analysis of 125 cells are presented. The aim of this work is to establish Q-banding patterns and make a detailed study of chromomere counting and distribution. To obtain Q-bands Quinacrine and Pseudoisocyanine staining techniques have been used.

D008540	Meiosis	A type of CELL NUCLEUS division, occurring during maturation of the GERM CELLS. Two successive cell nucleus divisions following a single chromosome duplication (S PHASE) result in daughter cells with half the number of CHROMOSOMES as the parent cells.

D011796	Quinacrine	An acridine derivative formerly widely used as an antimalarial but superseded by chloroquine in recent years. It has also been used as an anthelmintic and in the treatment of giardiasis and malignant effusions. It is used in cell biological experiments as an inhibitor of phospholipase A2.

D002877	Chromosomes, Human	Very long DNA molecules and associated proteins, HISTONES, and non-histone chromosomal proteins (CHROMOSOMAL PROTEINS, NON-HISTONE). Normally 46 chromosomes, including two sex chromosomes are found in the nucleus of human cells. They carry the hereditary information of the individual.
