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.

why do you use a graduated cylinder to measure out the desired volume of koh and h2so4, rather than a pipet or a buret?
sergey [27]

The graduated cylinder is used to measure the volume of KOH and H2SO4 when accurate volume measurement is not required.

In the laboratory certain graduated apparatus are used to measure liquids. These graduated apparatus used to measure liquids include;

  • burette
  • pipette
  • measuring cylinder
  • Erlenmeyer flask

Sometimes, we are not really looking for a strictly accurate volume of liquid and we can use a graduated cylinder to measure the volume of liquid in such cases.

However, when we need to have strictly accurate volume measurement, we need a pipet or a buret.
