3. following digestion of a dna sample with restriction enzymes and separation of the resulting fragments by electrophoresis, one often uses dna probes and a blotting procedure to identify the fragment containing the gene of interest. this process is known as
southern blotting. (probing dna fragments with dna probes is an approach developed by edwin southern)

The correct answer will be- true

Explanation:

The technique to identify the particular segment of DNA from the other DNA segment is known as the southern blotting.

The technique was developed by the Edwin Southern by transferring the electrophoresis DNA fragments to the nitrocellulose sheet and then separating them by probe hybridization.

The technique was the first method which was used to identify the particular segment of the DNA and thus is true is the correct answer.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
