Chromosome 21 Reveals Sparse Gene Content
Ricki Lewis | Jun 11, 2000 | 8 min read
The unveiling of the DNA sequences of human chromosomes represents a new chapter in the unfolding story of genomics, but one with roots in the half-century-old field of cytogenetics. Chromosome-level looks can reveal the specific genes behind certain traits and disorders while providing information on genome organization. The diminutive chromosome 21--the smallest of the human contingent, despite its number as next to last--is the fourth to be described. Its debut in mid-May attracted attentio

The Science Of Sex: What Is It And Who's Doing It?
Neeraja Sankaran | Mar 20, 1994 | 9 min read
Although it is a widespread field of study, sex research-- particularly that dealing with human sexuality--is still subject to stigma, many scientists agree. "It's okay to use sex for advertising--Pepsi, beer, and Calvin Klein jeans--but when it comes to research, sex is still a bad word," says Robert Friar, a professor at Ferris State University in Big Rapids, Mich., where he teaches anatomy and physiology and a course on human s

Telomere Findings May Yield Tips For Treating Cancer, Geriatric Disorders
Ricki Lewis | Feb 18, 1996 | 7 min read
Geriatric Disorders Author: Ricki Lewis SIDEBAR : TELOMERE BIOLOGY RESOURCES Chromosome tips, called telomeres, have long fascinated geneticists because they protect chromosomes from degradation. And recent research has revealed another vital role for telomeres: As they shrink with each cell division, they keep a biochemical tally of the number of divisions remaining in a cell's lifetime. If this precise control goes awry, the biochemical consequences could be dire, such as uncontrolled growt
