Researchers at the J. Craig Venter Institute (JCVI) have announced the results of work on genome transplantation methods allowing them to transform one type of bacteria into another type dictated by the transplanted chromosome. The work, published online in the journal Science, by JCVI’s Carole Lartigue, Ph.D. and colleagues, outlines the methods and techniques used to change one bacterial species, Mycoplasma capricolum into another, Mycoplasma mycoides Large Colony (LC), by replacing one organism’s genome with the other one’s genome.
But, if you think about it as “transplanting the cell membrane and wall of one species onto another” than it does not sound so epochal, does it?
The first pigs containing genes responsible for Alzheimer’s disease will be born in Denmark in August. This event is a landmark achivement in the effort towards finding a cure for the disease.
Large, seemingly useless pieces of RNA – a molecule originally considered only a lowly messenger for DNA – play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.
