We suggest that a difference in recombination adopted by these organisms in response to the deleterious effects of interspersed repeated DNA can explain in part this fundamental difference between the evolutionary dynamics of fruit fly and human retrotransposons....
Every individual has their own unique identity because of the specific structure and nature of the DNA within the cell. Answer and Explanation: Humans share 60 percent DNA similarity with fruit flies and 97 percent similarity with mice Humans, fruit flies, and mice are three different......
"Then when you swap the diet back to a high protein diet, the flies with the mutation go down in numbers and the other flies without the mutation go up." Given that humans share 75 percent of the same genes as fruit flies, and have the same mtDNA genes, "it is certainly an intrigui...
A person's skin and a fruit fly's exoskeleton, called a "cuticle" may not look alike, but both coverings protect against injury, infection, and dehydration. The top layers of mammalian skin and insect cuticle are mesh-works of macromolecules, the mammal version consisting mostly of keratin pr...
Over 15 years ago, researchers found that insects, and fruit flies in particular, feelsomething akin to acute paincalled “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain. ...
The Drosophila melanogaster genome codes for lamin B-type (lamin Dm), lamin A-type (lamin C), and for LEM-domain proteins, BAF, LINC-complex proteins and all typical nuclear proteins. The fruit fly system is simpler than the vertebrate one since in flies there is only single lamin B-...
But rice beats both fruit flies and humans, with 62,435 genes, and it is hard to argue that rice are 3–5 times as complex as humans or fruit flies. So if the sheer number of genes doesn't account for differences in organismal complexity, what does? The answer is that we don't ...
mainly fruitflies ( drosophila melanogaster ), nematode worms ( caenorhabditis elegans ) and zebrafish ( danio rerio )— enables the rapid and cost-effective assessment of the effects of gene variants, which can then be validated in mammalian model organisms such as mice and in human cells. by...
The genetic distance between humans and chimpanzees, based on electrophoretic comparison of proteins encoded by 44 loci is very small, corresponding to the genetic distance between sibling species of fruit flies or mammals. Results obtained with other biochemical methods are consistent with this ...
In previous work, Dr. Ding had shown that RNAi contributed to antiviral defense in embryonic stem cells and in newborn mice. He also was the first to describe the action of the influenza virus protein NS1 in blocking RNAi in fruit flies. These findings still left scientists uncertain of whet...
