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.

one centimetre is equal to 0.01 metres

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
