Protein helps cells duplicate correctly, avoid becoming cancer
A Purdue University researcher has discovered that the absence of certain proteins needed for proper cell duplication can lead to cancer. view more (2009-10-06)
'Birth control' for centrioles
Like DNA, centrioles need to duplicate only once per cell cycle. Rogers et al. uncover a long-sought mechanism that limits centriole copying, showing that it depends on the timely demolition of a protein that spurs the organelles' replication. view more (2009-01-26)
A tumor of the pancreas mimicked by colonic duplication?
A case of cystic colonic duplication in an adult mimicked a tumor of the pancreas and the diagnosis was established by histopathological examination of the resected specimen after distal pancreatectomy. view more (2008-03-13)
DNA replication behavior in complex organisms may foreshadow leaps in genomic discoveries
For the first time, findings by scientists at the Genome Institute of Singapore (GIS) may be paving the way for more efficient analyses and tests related to the replication of cells, and ultimately, to the better understanding of human biology, such as in stem cell research. view more (2007-08-16)
Ancestral genome of present-day African great apes & humans had burst of DNA sequence duplication
The genome of the evolutionary ancestor of humans and present-day apes underwent a burst of activity in duplicating segments of DNA, according to a study to be published in Nature Feb 12, the 200th anniversary of Charles Darwin's birthday. view more (2009-02-12)
CSHL scientists discover link between control of chromosome duplication and segregation
Before a cell can divide into two, first it must duplicate its genetic material--the DNA packed in its chromosomes. The two new sets of chromosomes then have to be separated from one another and correctly distributed to the resulting "daughter" cells, so that both daughter cells are genetically identical to the original, or... view more...

Public collections of DNA and RNA sequence reach 100 gigabases
The world's three leading public repositories for DNA and RNA sequence information have reached 100 gigabases [100,000,000,000 bases; the 'letters' of the genetic code] of sequence. view more (2005-08-23)
Newly found DNA catalysts cleave DNA with water molecule
Better tools for manipulating DNA in the laboratory may soon be possible with newly discovered deoxyribozymes (catalytic DNA) capable of cleaving single-stranded DNA, researchers at the University of Illinois say. view more (2009-08-17)
Genetic abnormality may increase risk of blood disorders
Researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) have shown for the first time that a tendency to develop some blood disorders may be inherited. view more (2009-03-16)
DNA-Proofed Documents To Arrive 'By 2006'
The commercial launch of the first ever fool-proof document security system is planned for 2006, reports Marina Murphy in Chemistry & Industry magazine. The system, which uses DNA fingerprinting, will allow documents to be authenticated with an accuracy of billions to one against duplication, according to the Australian scientists working on... view more...

Massive Duplication of Genes May Solve Darwin's "Abominable Mystery" about Flowering Plants
Researchers from the Floral Genome Project at Penn State University, with an international team of collaborators, have proposed an answer to Charles Darwin's "abominable mystery:" the inexplicably rapid evolution of flowering plants immediately after their first appearance some 140 million years ago. view more (2006-05-11)
New technique could dramatically lower costs of DNA sequencing
Using computer simulations, researchers at the University of Illinois have demonstrated a strategy for sequencing DNA by driving the molecule back and forth through a nanopore capacitor in a semiconductor chip. The technique could lead to a device that would read human genomes quickly and affordably. view more (2007-12-13)
More 'functional' DNA in genome than previously thought
Surrounding the small islands of genes within the human genome is a vast sea of mysterious DNA. While most of this non-coding DNA is junk, some of it is used to help genes turn on and off. view more (2007-12-12)
Protein splicing upsets the DNA colinearity paradigm
Understanding medical research problems often relies on the direct, linear relationship between the sequence of a protein and the DNA encoding that protein. view more (2006-09-08)
Is DNA Repair a Substitute for Sex?
Birds and bees may do it, but the microscopic animals called bdelloid rotifers seem to get along just fine without sex, thank you. What's more, they have done so over millions of years of evolution, resulting in at least 370 species. These hardy creatures somehow escape the usual drawback of asexuality - extinction - and the MBL's David Mark... view more... (2008-04-03)
Which came first, the chicken genome or the egg genome?
Which came first, the chicken genome or the egg genome? Researchers have answered a similarly vexing (and far more relevant) genomic question: Which of the thousands of long stretches of repeated DNA in the human genome came first? And which are the duplicates? view more (2007-10-09)
DNA analysis reveals rapid population shift among Pleistocene cave bears
Studying DNA obtained from teeth of ancient cave bears, researchers have been able to identify a shift in a particular population of the bears inhabiting a European valley in the late Pleistocene era. view more (2007-02-20)
International consortium announces the 1000 Genomes Project
An international research consortium today announced the 1000 Genomes Project, an ambitious effort to sequence the genomes of at least 1000 people to create the most detailed and medically useful catalogue to date of human genetic variation. view more (2008-01-23)
New tool helps researchers identify DNA patterns of cancer, genetic disorders
A new tool will help researchers identify the minute changes in DNA patterns that lead to cancer, Huntington's disease and a host of other genetic disorders. view more (2009-05-19)
Researchers Find Synthetic Molecules That May Literally Be The Key To “Locking Away” Unwanted DNA
Research chemists have a found a class of synthetic molecules that could quite literally act as a key which could lock away sections of DNA into a closely wound coil preventing proteins from interacting with particular sections of DNA code. By locking up the DNA in this way scientists could stop particular sequences of DNA from activating... view more... (2002-04-15)
