DNA is made up of monomers called nucleotides. How many does mono- represent?
Lunna [17]

Answer:

It is often said that life is “carbon-based.” This means that carbon atoms, bonded to other carbon atoms or other elements, form the fundamental components of many, if not most, of the molecules found uniquely in living things. Other elements play important roles in biological molecules, but carbon certainly qualifies as the “foundation” element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.

Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
