Carnivorous Plant Gets Rid Of Its Junk DNA
2013-05-13 11:22:44

Brett Smith for redOrbit.com — Your Universe Online There are approximately 3 billion base pairs in the human genome, however, only about 2 percent of those are actual genes. The rest is considered ℠junk´ DNA. For years, scientists have puzzled over the question of why so much of the human genome appears to be useless, and a new study on a bizarre wetland plant could be the key to solving the genetic mystery. Utricularia gibba is a carnivorous plant that...

A single gene mutation can sweep through a population, opening the door for the concept of 'species' in bacteria Bacteria are the most populous organisms on the planet. They thrive in almost every known environment, adapting to different habitats by means of genetic variations that provide the capabilities essential for survival. These genetic innovations arise from what scientists believe is a random mutation and exchange of genes and other bits of DNA among bacteria that sometimes...

More than just packaging, the genome affects the way our genes change and develop, says a TAU researcher Since Charles Darwin first put forth the theory of evolution, scientists have been trying to unlock the mysteries of genetics. But research on the genome – the organism's entire hereditary package encoded in DNA and RNA – has been less extensive. There is a tendency to think of the genome as a static and passive container of information, says Dr. Ehud Lamm of Tel Aviv...

The smallest collection of genes ever found for a cellular organism comes from tiny symbiotic bacteria that live inside special cells inside a small insect. The bacteria Carsonella ruddii has the fewest genes of any cell. The bacteria's newly sequenced genome, the complete set of DNA for the organism, is only one-third the size of the previously reported "smallest" cellular genome. "It's the smallest genome -- not by a bit but by a long way," said co-author Nancy A. Moran, UA Regents'...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
