I believe it's stem cells.
In plants, photosynthesis, occurring in chloroplasts, is an anabolic (bond-building) process whereby CO2 and H2O combine with the use of light (photon) energy. This yields O2 and sugar (i.e. glucose). This occurs in 2 phases: light-dependent and dark (Calvin cycle) reactions, which both continually recycle ADP/ATP and NADP/NADPH.
The catabolic (bond-breaking) process in plants is cellular respiration, in which glucose is broken down with O2 by glycolysis (cytoplasm only) and mitochondrial reactions (Krebs cycle and E.T.C.) to yield CO2 and H2O. These reactions recycle ADP/ATP and NAD/NADH. The CO2 and water produced by cellular respiration feed into the photosynthetic processes, and in turn, the O2 and glucose resulting from photosynthesis supply the respiratory reactions.
The vector that would be the
best choice for cystic fibrosis gene therapy is adeno-associated virus for it
has valuable reasons. First, it is huge enough to carry the gene, second, it
will infect the right type of tissue, third, it will not cause an immune
response and lastly, it infects the particular cells that divide irregularly. Therefore,
this vector will definitely treat cystic fibrosis for it can target affected
cells, which is a great help in the normal functioning of an organ.
