E. coliwith dsDNA labeled with radioactive thymidine, allowed to replicates in a simple nutrient medium for two-generation. What will be the percentage of bacteria containing only non-radioactive DNA?
Options:
Answer:
D
Solution:
DNA replication is the process of making a duplicate copy DNA. This process is semi-conservative where one strand of DNA is new strand and other is old.
When E.coli with dsDNA labeled with radioactive thymidine is allowed to replicate in simple nutrient medium for two generation, 50% will be non-radioactive DNA.
