阅读理解 Scientists in Argentina have created the world’s first cow to own two human genes that
will enable it to produce human-like milk, which is matchless up to now. It is a breakthrough
in the area of clone.
Genetic engineering was used to introduce the "mothers’milk" genes into the animal
before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.
As an adult the cloned cow "will produce milk that is similar to humans" in what will
prove "a development of great importance for the nutrition of infants", it said in a statement.
"The cloned cow, named Rosita ISA, is the first one born in the world that owns two
human genes that contain the proteins present in human milk," the statement said.
In April, scientists in China published details of research showing that they had
created GM Holstein dairy cows which produced milk containing proteins found in human
But the Argentine team says the Chinese only i
