In STR profiling, PCR is used to obtain enough DNA to then detect the number of STRs at I specific loci.​
Licemer1 [7]

PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.

<h3>What is Short Tandem Repeat (STR) profiling?</h3>

Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.

The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.

Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.

Why do intraplate earthquakes tend to be less frequent and smaller than earthquakes at plate boundaries?
Inga [223]
Earthquakes on plate boundaries happen more because the plates all move in different directions in a tectonic environment so they collide against each other which makes them more frequent. Earthquakes rarely happen in intra-plate environments but along faults in normally stable interior of the plates. If this doesn't make sense, ask me to reword it for you !

How do magnetic stripes of iron in ocean rock provide evidence of seafloor spreading
STatiana [176]

Answer:

In the 1960s, scientists found evidence that new material is indeed erupting along mid-ocean ridges. The scientists dived to the ocean floor in Alvin, a small submarine built to withstand the crushing pressures four kilometers down in the ocean. In a ridge’s central valley, Alvin’s crew found strange rocks shaped like pillows or like toothpaste squeezed from a tube. Such rocks form only when molten material hardens quickly after erupting under water. These rocks showed that molten material has erupted again and again along the mid-ocean ridge.

When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history. The last reversal happened 780,000 years ago. If the magnetic poles suddenly reversed themselves today, you would find that your compass needle points south.

Explanation:

I found this somewhere.
