Answer:
Answer is explained below.
Explanation:
The DNA (deooyrtonucleic acid) molecule undergoes replication in conservative manner
The two strands separate, a new strand is synthesized by the incorporation of nucleotides followed by ligation.
Thus, in the daughter double helix, one of the strand is newly synthesized So. whet replication occurs in vitro , with the help of radioactive phosphate, me newly synthesized strand can be traced .A detailed diagram of the DNA replication in a medium contain radioactive phosphate is shown in attached image.
The blue dotted ones are the sequence of nucleotides incorporated. The parent template with
non-radioactive phosphate (solid line) is copied in the daughter cells. This is consistent with the
Messelsion and Stahl experiments. In the next cycle, the hybrid strands separate and act as
template, in which a hybrid strands and a non-hybrid strands with radiophosphates on either
strands is formed.
With the cycles of replication, the strand with radioactive isotopes increase compared to the
mother strand with non-radioactive phosphates.
