It takes only half a billion rubles to breed a herd of transgenic goats

This is almost 2 times more than spent on the first stage of the program. This is due to the fact that the second stage provides for higher costs for the construction of farms for the maintenance of transgenic herds, the creation of industrial herds of animals themselves – producers of human medicinal proteins, the development of technologies for the isolation of human proteins from animal milk and the creation of medicinal, food and perfumes with the organization of their pilot production.

Three, six, code

Two nucleotides are connected by a strong covalent bond, and with the third and the amino acid – by weak physico-chemical bonds. To strengthen this connection, we need another three – complementary. It will turn out to be a six, which will be supported by hydrogen bonds between complementary nucleotides.

Stem cells: How to distinguish science from myth-making? (1)

The information circulating in the media that scientists have received the Nobel Prize in Physiology and Medicine for discoveries in the field of stem cells is rekindling interest in mysterious cells, both among specialists and among ordinary people. Since there are already a lot of myths on the Internet and scientists dealing with this problem, there are also a certain number of charlatans who use the moment to earn money and fame.

World Community Grid: Join the Distributed Computing network!

There are about 650 million personal computers in the world, and most of them use only a small part of their power when working. At the same time, these untapped resources can be used for the benefit of all mankind. To this end, in 2004, the World Community Grid system was created – the largest global computing system for solving the most important humanitarian problems.

The shelf of genes has decreased

By the time the "draft" sequence of the human genome was published in 2001, the figure 35,000 was generally accepted, but now genetic catalogs include approximately 24,500 genes. A new bioinformatic study shows that the number of "real" genes is even smaller: about 20,500.
