How Would You Label and Separate the DNA of Unknown

Question

How would you label and separate the DNA of unknown methylotrophs in a sample?
A) Incubate the sample with ¹³C-methane.
B) Hybridize the DNA to FISH probes.
C) Use DGGE to separate the strands of DNA in the sample.
D) Use T-RFLP to identify the methylotroph DNA in the sample.

Accepted Answer

Methylotrophs can incorporate ¹³C from ¹³C-methane into their DNA, allowing for the separation and identification of their DNA based on the incorporation of the heavy isotope.
