DNA segment in which both transfer label with 15N is transfer the 14N medium and allow it to replicate 3 times.How many daughter molecules show both the strands with 14N
Answers
Hey mate here's your answer :
6 daughter molecules will be formed after 3 times replication where both the strands carries 14N .

After the first replication the DNA strand of 15 medium gets a strand of 14 medium each. Again these two DNA molecule undergoes 2nd replication where each of the 4 DNA strands gets another 14 medium DNA strand added which gives us 4 molecules of DNA. Under the same procedure the 4 DNA molecules divides the third time giving 8 molecules from which 6 pairs has 14 medium labelled in both of their strands.
Hope this helps you dear.
WISH YOU LUCK!!
