Japanese scientists were able to change mouse fibroblasts into induced pluripotent stem cells (IPS), a type of stem cell that is similar to embryonic stem cells. The researchers were then able to grow heart and brain cells
from these stem cells. Which conclusion is best supported by the results of the scientists?
o A. IPS cells can be made from embryonic cells.
B. IPS cells can be made from adult cells.
o C. Embryonic cells cannot be used to grow iPS stem cells.
O D. Mouse fibroblasts will naturally grow into specialized IPS stem cells.

this protocol provides a detailed procedure for chromatin immunoprecipitation (chip) to study the dna-protein interactions.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
