The Rosetta Stone
Gregory A Petsko Genome Biology 2001, 2:comment1007-comment1007.2 (1 May 2001)
Full text | PDF | PubMed
|
Editor’s summary
Few things can cause so much trouble, especially in scientific discourse, as metaphor. Various metaphors have been used for the human genome project: the sequence would represent a blueprint for building a human being or would be like an encyclopedia. I think the best metaphor is the Rosetta Stone.

Morpholino antisense oligonucleotides: tools for investigating vertebrate development
David R Corey, John M Abrams Genome Biology 2001, 2:reviews1015-reviews1015.3 (26 April 2001)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
Antisense oligonucleotides provide a promising approach to investigating gene function in vivo, but their ability to offer unambiguous insights into phenotypes has been debated. The recent use of morpholino antisense oligonucleotides in zebrafish embryos may prove a major advance, but rigorous controls are essential.

Abstract | Full text | PDF | PubMed
|
Editor’s summary
A few dozen genes are known on the human Y chromosome. The completion of the human genome sequence will allow identification of the remaining loci, which should shed further light on the function and evolution of this peculiar chromosome.
