DNA is copied in a process called DNA replication. During DNA replication, the two strands of the DNA molecule separate. Then free DNA nucleotides pair with their complimentary nucleotides according to the base-pairing rule on each of the old strands of DNA. Once the process is complete, the result is two identical DNA molecules, each with one old strand of DNA and one new strand of DNA. Refer to the related link for an illustration.
you need many copies of DNA for DNA fingerprinting
The process of creating new copies of DNA is called DNA replication. During replication, the double-stranded DNA unwinds and each strand serves as a template for synthesizing a new complementary strand. This process is essential for cell division, ensuring that each new cell receives an identical copy of the DNA.
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
DNA replicates using the process called semiconservative replication. An original DNA molecule is complementary to the replicated molecule, which means that they are identical copies of each other.
PCR made it possible to produce enough copies for reliable tests.

Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)
Amplification is the production of many copies of a particular DNA segment. The copying repeats - so that copies of the copies are made. This results in many, many copies in only a few cycles. PCR (Polymerase Chain Reaction) is the most common method of amplifying DNA.
Unless mutation occur the two copies of DNA that are made after replication are identical to its original form. Thus continuous replication of DNA in the chromosomes does not alter its nature.
it copies a code from the DNA
Messenger RNA (mRNA) copies DNA's instructions in the nucleus.
