2021天一大联考高二一联答案
  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 that of humans", which will prove "a
development of great importance for the nutrition of infants(婴儿)," said the institute. "the cloned cow, named rosita isa,
is the first in the world with two human genes that contain the proteins
present in human milk," said the statement.

    in april, scientists in china published
details of research showing that they had created dairy cows which produced
milk containing proteins found in human breast milk. but the argentine team
said the chinese only introduced one human gene, while their research involved
two, meaning the milk will more closely
resemble that of humans. 

    "our goal was to raise the nutrition
value of cows' milk by adding two human genes, which do good to the immune
system of infants," said adrian mutto, from the national university of san
martin which worked with the institute.
