The Duplication of Chromosomes
Scientific American, 1958Chromosome duplication first of all requires the replication of the DNA. It is now clear that the replication of most if not all of the chromosomal DNA follows the scheme based on precise base pairing as originally proposed by Watson and Crick [50].

JAMA: The Journal of the American Medical Association, 1970
To the Editor.— Tjio et al (210:849, 1969) have made an important methodological advance in the study of the effects of lysergic acid diethylamide (LSD) on human chromosomes in vivo by measuring chromosome aberration rates in subjects both before and after LSD administration. The authors were unable to conclude that LSD had a harmful effect.

Sex Chromosomes and Sex Chromosome Abnormalities
Clinics in Laboratory Medicine, 2011This article focuses on constitutional sex chromosome abnormalities detected by conventional cytogenetics and fluorescence in situ hybridization. The author discusses the two general classifications of abnormalities: numerical and structural. Also included are descriptions of unique aspects of X and Y chromosomes, technological advances in detection ...

Ring-Chromosomes, Telocentric Chromosomes, Isochromosomes, and B Chromosomes
1980This chapter is a continuation of the discussion of unusual chromosome types. As mentioned before, the term “unusual” in this connection is a relative term. We very often have a certain concept of things, and whatever deviates from this concept we call “unusual”. Because ring-chromosomes, telocentric chromosomes, isochromosomes, or B chromosomes differ

Abstract Chromosome studies in hematological disorders made rapid and significant advances following the introduction of banding techniques and the most salient features of these studies are succinctly reported in this Review. Considering the consistency of the chromosome anomalies first, it appears that about 50% of the acute leukemias do not present
