No because It's difficult enough to get a single molecule to freeze, let alone a group of connected molecules, so crystallography is usually limited to single proteins, parts of proteins, or tightly bound molecules.
Some people have therefore looked to telomerase as a molecular “fountain of youth,” reasoning that if we could get it working in adult cells, we could potentially elongate life. However, there's good reason why telomerase isn't expressed in all cells – allowing cells to replicate without end isn't good.
Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell.
