The new strands took only non-radioactive bases during their replication. This implies that the radioactive bases did not get incorporated in the new strands. Also, according to semi-conservative mode of replication, one parental and one newly synthesized strand goes to the daughter cells. Since it is a hypothetical situation according to which parental strand has radioactive labeling, the radioactive strand will pass on to both the daughter cells.
The formation of new DNA from the old DNA is called replication. DNA contains all the information that is required to form and function the human body.
DNA is made up from:-
When DNA replicates from the old DNA it always has one strand from the parent cell and one strand of DNA is newly formed. This is called Semi conservation of DNA.
Hence, one strand of the DNA has a nitrogenous base which proves the semi-conservation nature of DNA.
