Massive duplication of genes may solve Darwin's 'abominable mystery' about flowering plants

Researchers create genetically matched embryonic stem cells for transplantation

...may have some regions of their genome that contain duplicated copies of mutant genes that have been linked with malignancies or abnormal tissue growth. "Right now this technique is useful for basic research, but we are hopeful that parthenogenetic cells might prove useful for therapies," Daley says. "Our cell...

Single molecular 'mark' seen as pivotal for genome compaction in spores and sperm

...es occur in the genetic material after it has been duplicated and then halved on the way to the production of mature gametes or spores. Near the end of the process, the material ?called chromatin, the substructure of chromosomes ?becomes dramatically compacted, reduced in volume to as little as five percent of ...

Genome archaeology illuminates the genetic engineering debate

...genomes today contain rearranged segments and many duplicated regions with corresponding sets of genes. In the maize genome, genes were apparently lost in some parts and new "stuffer" pieces (intervals between genes) inserted so that the corresponding segments became different in size. The researchers found ...

New clues to how sex evolves

...throughout the genome in all species, but unless a duplicated gene quickly acquires a new function, it is not likely to be conserved. The group of related zinc-finger protein genes in C. elegans offers an opportunity to address the question of how and why new zinc-finger proteins acquire new functions." A ...

Novel experiment documents evolution of genome in near-real time

... the two mutant genes into the original strain and duplicated the faster growth rate. "We expected to find many mutated genes and we thought our results would be very difficult to understand, but neither was the case," said Christopher D. Herring, a co-author of the paper and a former member of Palsson's team w...

Chromosomal microarray analysis proves accurate

...tic material that show imbalances because they are duplicated or deleted abnormally with gains and losses of genetic information. "If these changes are big enough, they can cause significant disabilities," said Beaudet. The technique used is also much more efficient, making it possible to do the equivalen...

Cancer scientists create 'human' leukemia process to map how disease begins, progresses

...ppened. "With the method we developed, we have duplicated the natural process every step of the way. The method we developed opens the pathway generally to understanding the process of how cancer begins." The scientific team of Frederic Barabe, James Kennedy and Kristin Hope introduced a specific leuk...

How fish conquered the ocean

... ?the degradation of yolk proteins from one of the duplicated genes causes the eggs to fill with vital water and...the function (neo-functionalization) of one of the duplicated genes (paralogues) allowed its yolk protein products to be broken down to free amino acids and thus ...

Making mice with enhanced color vision

...ch as humans, the two different X chromosome genes duplicated so that each X chromosome now carries the genes for both receptor types, giving both males and females trichromatic color vision. "You could say that the original primate color vision system, and the one that New World monkeys still use today, is...

Latent memory of cells comes to life

... new double-strand. Nucleosomes though are not duplicated like the DNA-strands. Rather, they are distributed between the two new DNA double strands and the empty spaces are filled by new nucleosomes. Cell division is therefore an opportunity for changes in the nucleosomal composition of a specific DNA regio...

Mutating the entire genome

... desired large stretch of DNA is either deleted or duplicated so scientists can see what goes wrong in the mutant mouse and thus learn the normal job of that piece of DNA. Capecchi says the same method also can be used to make two chromosomes break and recombine, with each new chromosome containing a piece ...

Exploring the dark matter of the genome

...ecome inactive, most likely because they have been duplicated or code for traits no longer needed by the organism. Drosophila has very few pseudogenes compared to most complex organisms (humans have some 20,000), but the annotators found 32 new ones in the heterochromatin, more than twice as many as previously ...
