Article: We know, painkillers in a tablet can make your headache go away, and antibiotic from a tube can prevent your cuts from becoming infected. Can medicine come in chicken eggs? A team of scientists from Scotland says "yes." They've kept some special chickens that lay eggs with disease-treating drugs inside. These drugs are made of molecules called proteins. Animals make thousands of proteins--they're the main ingredients in skin, hair, milk, and meat. Since animals can make proteins easily, they're good animals for making protein drugs. Researchers have already made cows, sheep, and goats that pump out protein drugs in their milk. But chickens are cheaper to take care of, need less room, and grow faster than these other animals. "Those qualities could make chickens a better choice to become living drug factories." says Simon Lillico of the Roslin Institute near Edinburgh, Scotland. Lillico and a team of researchers changed chickens' DNA--the code that tells cells how to make proteins--so that the birds' cells made two protein drugs. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis. The scientists changed the chickens' DNA so that the birds made these drugs only in their egg whites. This protects the chickens' bodies from the drugs' possible harmful effects and makes it easy for scientists to collect the drugs. These special chickens can pass on their drug-laying abilities to their chicks. So far, the Scottish researchers have kept five generations of drug-producing chickens. But the scientists need to improve these chickens. The chickens don't make enough drugs to treat people yet. Once the researchers perfect their technique, you might eventually take your medicine from chicken eggs. Question: What can be inferred from the passage? Yes or no, is the answer "This technique still needs improving so as to satisfy the normal application."?
The answer to this question is:
No
