BIOL - DNA Replication 

Semi-conservative Replication

1. The hydrogen bond between two DNA strands breaks down and the two DNA strands are separates. The two DNA strands exist as ¹⁵N.😃

2. The two DNA strands exist as ¹⁵N.😃. These two template strands are placed in a culture with free nucleotides in them. By complementary base pairing free nucleotides were attached to each template strand.

3. For the first division, DNA molecule contain a mix of ¹⁵N and ¹⁴N.​For the second division, DNA molecule consist solely of ¹⁴N and mix of ¹⁵N and ¹⁴N . 😁

4. For, semi-conservative as seen from the picture it has to contain DNA molecule mix of ¹⁵N and ¹⁴N and solely of ¹⁴N .

5. Finally, the DNA strand contains one template strand and one newly synthesized complimentary strand and the other one contains second parent strand and one newly synthesized complimentary strand.
