Question

Tandem mass spectrometry is used to obtain _____.

Answer 1

Tandem mass spectrometry (MS/MS) and Edman degradation are the two most widely used techniques for obtaining sequence information from proteins.

Answer 2

Answer:

DNA fingerprints

Explanation:

Tandem mass spectrometry is used to obtain DNA fingerprints as it is used for sequencing of both DNA and RNA.

It involves multiple fragmentation.

In this mass spectrometry, the substrate is first converted to ions and then the ions are separated based on mass to charge ratio. Now these ions separated are further processed for fragmentation producing daughter or product ions. These are again separated and analyzed based on mass to charge ratio.
