University of Utah University of Utah researchers find that multiple silent mutations greatly impact protein translation So-called silent DNA mutations earned their title because, according to the fundamental rules of biology, they should be inconsequential. Reported on June 5 in PLOS Genetics online, University of Utah researchers experimentally proved there are frequent exceptions to the rule. The work was conducted in the bacteria, Salmonella enterica, used to study basic biological...

DOE/Joint Genome Institute In the Lewis Carroll classic, Through the Looking Glass, Humpty Dumpty states, "When I use a word, it means just what I choose it to mean—neither more nor less." In turn, Alice (of Wonderland fame) says, "The question is, whether you can make words mean so many different things." All organisms on Earth use a genetic code, which is the language in which the building plans for proteins are specified in their DNA. It has long been assumed that there is only one...

The United States market for amino acids was valued at $1.5 billion in 2012 and was estimated at nearly $1.6 billion for 2013. BCC Research expects the market to grow to nearly $2 billion by 2018, and register a five-year compound annual growth rate of 4.5% from 2013 to 2018. Wellesley, Mass (PRWEB) March 10, 2014 According to a new technical market research report Commercial Amino Acids, from BCC Research (http://www.bccresearch.com), the United States market for amino acids was valued...

Anne D. Holden, PhD - Gladstone Institutes Gladstone's innovative technique in stem cells to boost scientists' ability to study - and potentially cure - genetic disease Sometimes biology is cruel. Sometimes simply a one-letter change in the human genetic code is the difference between health and a deadly disease. But even though doctors and scientists have long studied disorders caused by these tiny changes, replicating them to study in human stem cells has proven challenging. But now,...

Secret Code Discovered In Human DNA
2013-12-13 05:26:03

[ Watch the Video: Human DNA Has Been Hiding A Secret ] redOrbit Staff & Wire Reports - Your Universe Online A newly discovered ‘second code’ hiding within our DNA is casting new light on how changes to DNA impact health and disease, according to a study published Friday in the journal Science. The new code is changing the way scientists read and interpret genetic instructions and mutations. Since the genetic code was deciphered in the 1960s, scientists have assumed it...

Plug And Play Synthetic Biology - Rewriting An Entire Genome
2013-10-19 04:15:01

April Flowers for redOrbit.com - Your Universe Online A team of scientists from Harvard and Yale have recorded the entire genome of the bacteria E. coli, and in a dramatic demonstration of the potential of rewriting an organism's genetic code, they have improved the bacterium's ability to resist viruses. "This is the first time the genetic code has been fundamentally changed," according to Farren Isaacs, assistant professor of molecular, cellular, and developmental biology at Yale....

A new technique allows researchers to activate proteins in the brain by shining an LED light on them With the flick of a light switch, researchers at the Salk Institute for Biological Studies can change the shape of a protein in the brain of a mouse, turning on the protein at the precise moment they want. This allows the scientists to observe the exact effect of the protein's activation. The new method, described in the October 16 issue of the journal Neuron, relies on specially engineered...

How Rare 'Words' In Bacterial Genes Boost Protein Production
2013-09-27 07:29:50

Wyss Institute for Biologically Inspired Engineering at Harvard Scientists routinely seek to reprogram bacteria to produce proteins for drugs, biofuels and more, but they have struggled to get those bugs to follow orders. But a hidden feature of the genetic code, it turns out, could get bugs with the program. The feature controls how much of the desired protein bacteria produce, a team from the Wyss Institute for Biologically Inspired Engineering at Harvard University reported in the...

Near-optimal Genetic Code Model Created By Researchers
2013-08-29 04:15:01

redOrbit Staff & Wire Reports - Your Universe Online By creating a model of genetic code evolution, researchers have discovered new information about how RNA signaling could have developed into the “near-optimal” modern genetic code. Lead author Justin Jee, a doctoral student at NYU School of Medicine, and colleagues set out to account for the composition of the genetic code, which makes it possible for proteins to be constructed from amino acids with high specificity based on...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
