  • When the scientist want to make a DNA fingerprint but she has a very small DNA the next step she needs to perform is polymerase chain reaction (PCR).
  • The polymerase chain reaction is a technique which is used to make several copies of any desired DNA segment.
  • A single polymerase chain reaction cycle consists of many steps and this PCR cycle can be repeated many times to amplify the DNA sample and get several numbers of copies which can be up to millions.

proportional to the square of

the distance between them. (theory)

Human beings walk on the

ground rather than floating

in the air. (law)

Human beings walk on the

ground rather than floating

in the air because of Earth's

gravitational force. (fact)

Explanation:

theory: Us humans always come with theories so that it will make it a lot easier for us to understand the whole picture. So that's why the first part is a theory because we have never seen every particle attract an other particle. but because of the modern technology we are able to make a trustworthy theory.

Fact: We know that humans walk on the ground because of the earth's gravitational force.

law: This law mathematically describes how two different bodies in the universe interact with each other.

I hope this is ok :)
