An amino acid, such as glycine, that is found in the interior of a molecule after the polypeptide folds to a three-dimensional shape, will most likely have what defining characteristic?
a. unpaired electrons on the terminal r groups
b. one or more terminal oxygen atoms
c. one or more terminal nitrogen atoms
d. an arrangement of hydrocarbons

The correct answer is option d. "an arrangement of hydrocarbons".

Explanation:

Glycine is the simplest amino acid in terms of structure, as it has a single hydrogen atom in its side chain. A glycine found in the interior of a molecule after the polypeptide folds most likely will have the defining characteristic of being an arrangement of hydrocarbons. The interior of a polypeptide is defined by its hydrophobic nature, a non polar amino acid as glycine would contribute to the hydrophobicity by behaving as an arrangement of hydrocarbons.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
