Scientist determined that the fundamental unit of DNA was a nucleotide containing one of four possible bases, a sugar molecule, and a phosphate group was Levene.

Therefore, the correct answer to the question is option c.

Explanation:

DNA is responsible for the transfer of character from one generation to another generation. DNR the smallest structure present inside the nucleus of the cell. During the cell division the nucleus gets doubled and the chromosome also gets repeated.

DNA has a structure made of nucleoside base and sugar base. Changes made to DNA are responsible for the changes that is shown in the new generation. DNA replication is done at the time of producing of new generation.
