DNA Software Takes The Drudgery Out Of Molecular Biology

Author: RICKI LEWIS, p.23 It is expected to take some 15 years to determine the sequence of the 3 billion base pairs that make up the human genome--roughly 550,000 base pairs per day. An analytical task of this magnitude would have been unthinkable just a few years ago, but today's rapidly advancing computer technology has made the international effort to sequence the human genome possible.

©Mehau Kulyk/Photo Researchers, IncToward the end of World War II, a German-imposed food embargo in western Holland – a densely populated area already suffering from scarce food supplies, ruined agricultural lands, and the onset of an unusually harsh winter – led to the death by starvation of some 30,000 people. Detailed birth records collected during that so-called Dutch Hunger Winter have provided scientists with useful data for analyzing the long-term health effects of prenat

Data Mining Software for Genomics, Proteomics and Expression Data (Part 1) Data Mining Software for Genomics, Proteomics and Expression Data (Part 2) High-throughput (HT) sequencing, microarray screening and protein expression profiling technologies drive discovery efforts in today's genomics and proteomics laboratories. These tools allow researchers to generate massive amounts of data, at a rate orders of magnitude greater than scientists ever anticipated. Initiatives to sequence entire genom

The marker allows staining of the projections of these neurons into, among other areas, the hindbrain and spinal cord. (S.R.

DNA microarrays are one of the most promising answers to that cry. DNA microarrays are glass microslides or nylon membranes containing DNA samples (genomic DNA, cDNA,

Alternative Splicing Goes Mainstream
Sam Jaffe | Dec 14, 2003 | 10 min read
In eukaryotic genetics, the one-gene/one-protein concept has, for the most part, breathed its last. Researchers have rallied behind mechanisms such as alternative splicing, which may allow a lowly 30,000-gene genome to produce the dizzying variety of proteins that some believe is necessary to produce beings as complex as humans. Alternative splicing--the post-transcriptional editing process that can result in various mRNAs--was previously seen as an interesting but relatively uncommon sidesh

Think outside the cage." That's all it takes to understand why some researchers are moving away from mouse models and diving into transgenic fish research, according to biologist Richard N. Winn of the University of Georgia. Investigators bucking the mammalian tide come from all sectors of biological research, and, in addition to Winn, include National Academy of Sciences (NAS) member Richard B. Setlow, senior biophysicist at Brookhaven National Laboratory; Elwood A. Linney, professor of microbi
