Transplantation of MLC whole chromosome into M. cap cells//

J. Craig Venter institute

We started by isolating the chromosome from a cell called M. mycoides. Chromosomes are enshrouded with proteins, which is why there was confusion for so many years over whether the proteins or the DNA was the genetic material. We simply did what Avery did, we treated the DNA with proteolytic enzymes, removing all the proteins because if we’re making a synthetic chromosome, we need to know can naked DNA work on its own, or are there going to be some special proteins needed for transplantation? We added a couple of gene cassettes to the chromosome, one so we could select for it, and another so it turns cells bright blue if it gets activated. After considerable effort we found a way to transplant this genome into a recipient cell, a cell M. capricolum, which is about the same distance apart genetically from M. mycoides as we are from mice. So relatively close, on the order of 10 percent or more different.

Compose questions to the text given lower.

The donor genome encoded restriction enzyme degrades the recipient cell genome”

Let me show you what happened with this very sophisticated movie. We inserted the M. mycoides chromosome into the recipient cell. Just as with the Phi X, as soon as we put this DNA into this cell, the protein robots started producing mRNA, started producing proteins. Some of the early proteins produced were the restriction enzymes that Ham Smith discovered in 1970, we think that they recognized the initial chromosome in the cell as foreign DNA and chewed it up. Now we have the body and all the proteins of one species, and the genetic software of another. What happened?

Lesson 4 Topic: Curriculum Development. Curriculum Overview and Organisation

В США проводятся интенсивные научно-педагогические поиски, эксперименты и практические разработки содержания образования. Вся эта работа называется “Curriculum”, а развитие содержания образования “Curriculum Development”; “Curriculum Theory” – теория развития содержания образования.
