Harlamova29_29 [7]

Answer:

<h2> After one round: one strand of DNA  will contain radioactive 3232P, while the other strand  will not contain any radioactive phosphate. </h2><h2> After two rounds:  here 50%  of DNA will have 3232P in both strands, while 50% will contain 3232P in one strand and nonradioactive in the other strand. </h2>

 

Explanation:

1. In the initial sample which is immediately removed after addition of radioactive isotope of phosphorus ( 3232P), hence there is  no incorporation of 3232P into the DNA because replication in the medium containing 3232P has not yet occurred.  

2. After one round of replication in  radioactive isotope of phosphorus ( 3232P) containing  medium, here  only one newly synthesized strand of DNA molecule will contain 3232P, while the other strand  will not contain any  radioactive isotope of phosphorus ( 3232P),  because DNA replication occurs in semi-conservative way.

3. After two rounds of replication in medium which contains radioactive isotope of phosphorus ( 3232P), here 50% of the DNA molecules will have  radioactive isotope 3232P in both strands, while the rest 50% will contain 3232P in only one strand and nonradioactive phosphorous in the other strand.
