Question

In an experiment, you grow bacterial cells for several generations in the presence of a light isotope of carbon (C^12) and then transfer them into a medium containing a heavy isotope of carbon (C^13). After one round of DNA replication, which of the following statements is true? For all DNA molecules, one strand will be entirely labeled with C^12, whereas the other strand will be entirely labeled with C^13 All DNA molecules will be labeled entirely with C^12 Half the DNA molecules will be labeled with C^12 only, whereas the other half will be labeled with C^13 only. All DNA molecules will be labeled entirely with C^13 For all DNA molecules, each strand will be labeled with a mixture of C^12 and C^13.

Answer 1

for all dna molecule,each strand will be labelled with a mixture of c12 and c13
