Double chained DNA strand is made radioactive inboth its chains. It is...
Explanation:
When a double stranded DNA is made radioactive in both its chains, it means that both the strands of DNA will contain radioactive isotopes. These isotopes will be incorporated into the newly synthesized DNA strands during replication. When this double stranded DNA is allowed to replicate twice in a non-radioactive medium, the following outcomes are possible:
1. Conservative replication: The original double stranded DNA remains intact while a new double stranded DNA is synthesized. In this case, the newly synthesized DNA will contain radioactive isotopes while the original DNA will not.
2. Semi-conservative replication: Each of the original strands of DNA serves as a template for synthesis of a new complementary strand. In this case, one of the strands in the newly synthesized DNA will contain radioactive isotopes while the other strand will not.
3. Dispersive replication: The original double stranded DNA is broken into fragments, and each fragment serves as a template for synthesis of a new complementary fragment. In this case, some of the newly synthesized DNA fragments will contain radioactive isotopes while others will not.
Therefore, the result of allowing double stranded DNA to replicate twice in a non-radioactive medium will be that half of the strands will have radioactivity, as the semi-conservative replication is the most likely outcome.
