$DNA$ replication requires .........

Complementary $DNA$ $(cDNA)$ is complementary to

Describe the experimental proof for the semi-conservative mode of $DNA$ replication.

Replication was allowed to take place in the presence of radioactive deoxynucleotide precursors in $E. coli$ that was a mutant for $DNA$ ligase. Newly synthesised radioactive $DNA$ was purified and strands were separated by denaturation. These were centrifuged using density gradient centrifugation. Which of the following would be a correct result?

$DNA$ replicates semiconservatively. This was experimentally proven by:

What is the mode of $DNA$ replication in $E. coli$?
