Chromosome imprinting and the mammalian X chromosome [PDF]

Nature, 1975
Chromosome imprinting is the process by which one of two genetically homologous chromosomes is predetermined to function differently from the other at a subsequent stage in development. In the coccid insects, imprinting occurs in the egg, at the time of fertilisation; it probably occurs at the same time and site in mammals, and possibly also in Sciara.

Chromosomics

Cytogenetic and Genome Research, 2005
The term “chromosomics” is introduced to draw attention to the three-dimensional morphological changes in chromosomes that are essential elements in gene regulation. Chromosomics deals with the plasticity of chromosomes in relation to the three-dimensional positions of genes, which affect cell function in a developmental and tissue-specific manner ...

Lampbrush chromosomes

Journal of Cell Science, 1977
ABSTRACT 1986 was a celebration year for lampbrush chromosomes (LBCs), marked by the publication of Callan’s comprehensive and authoritative book on these structures. My commentary begins where Callan’s book ends, standing on tiptoe beside a large and rather neat assembly of well-established facts, principles and hypotheses, and trying ...

The human Y chromosome: a masculine chromosome

Current Opinion in Genetics & Development, 2006
Once considered to be a genetic wasteland of no scientific interest beyond sex determination, the human Y chromosome has made a significant comeback in the past few decades and is currently implicated in multiple diseases, including spermatogenic failure - absent or very low levels of sperm production.
