The seismic waves that travel through earth’s interior are waves.

The seismic waves that travel through Earth’s interior are known as the P waves and the S waves, these seismic waves have differences, first the P waves compress and enlarge the foundations(rocks) as they move through it, while the S waves, shakes the particles of their medium up and down and side-by-side. P waves can travel through solid granite, magma, water or even air, while S waves can only travel through solids, they are unable to travel through fluids. The P waves are the fastest of all known seismic waves, it is the first seismic wave to register on the seismograph, while the S wave is the second one.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
