(Phys.org)—Cell migration is an intrinsic feature of multicellular organisms, enabling such processes as embryo development, wound healing, and immune responses. These activities require cells to move freely within tissues. ...
Scientists at the Institute for Research in Biomedicine (IRB Barcelona) have found an explanation for a periodicity in the sequence of the genomes of all eukaryotes, from yeast to humans. The results published in the journal ...

Mitochondria are present in all eukaryotic cells: in our cells, in mammalian cells, in the cells of plants and even of fungi. Mitochondria produce energy for cells to function as multicellular organisms, and are known as ...
