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

The Human Genome: RNA Machine
John S. Mattick | Oct 1, 2007 | 7 min read
The Human Genome: RNA Machine Contrary to current dogma, most of the genome may be functional. John S. Mattick Related Articles 1 The idea of "junk DNA" is also based on the assumption that most genetic information is transacted via proteins, an assumption that dates back half a century to a time when the pioneers of molecular biology were studying bacteria, wherein most genes do indeed encode proteins. By contrast, protein coding sequences occupy only ~1.2% of the

Aminoacyl-tRNA synthetases, which help translate the genetic code into protein, also function in angiogenesis, fat metabolism, and more.
Rethinking Genetic Determinism
Paul Silverman | May 23, 2004 | 5 min read
Paul H. SilvermanCourtesy of Paul H. SilvermanFor more than 50 years scientists have operated under a set of seemingly incontrovertible assumptions about genes, gene expression, and the consequences thereof. Their mantra: One gene yields one protein; genes beget messenger RNA, which in turn begets protein; and most critically, the gene is deterministic in gene expression and can therefore predict disease propensities.Yet during the last five years, data have revealed inadequacies in this theory.
Pufferfish Genomes Probe Human Genes
Ricki Lewis | Mar 17, 2002 | 7 min read
It may be humbling to think that humans have much in common with pufferfish, but at the genome level, the two are practically kissing cousins. "In terms of gene complement, we are at least 90% similar—probably higher. There are big differences in gene expression levels and alternate transcripts, but if you're talking about diversity, number and types of proteins, then it's pretty difficult to tell us apart," says Greg Elgar, group leader of the Fugu genome project at the Medical Research C
