DNA is copied by breaking the hydrogen bonds keeping it together, separating itself into two complimentary strands. Lone base pairs in the nucleus attach to the now single stranded DNA, creating two identical strands of DNA.nnnlknlk A DNA molecule is copied in a process called DNA replication. During DNA replication, the enzyme helicase separates the two strands of DNA nucleotides. The nitrogen bases of the two strands of DNA nucleotides are exposed, and the enzyme DNA polymerase causes new DNA nucleotides to pair with the original, exposed nucleotides according to the base-pairing rule. The result is two identical DNA molecules, each having a new strand of DNA nucleotides, and an original strand of DNA nucleotides. This kind of replication is called semi-conservative replication.
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.
One method of making copies of DNA is through a process called polymerase chain reaction (PCR). In PCR, a DNA template is mixed with primers, nucleotides, and DNA polymerase, and subjected to cycles of heating and cooling to amplify the target DNA region. This results in millions of copies of the DNA target.
A cell does not make "extra copies" of DNA. Through a persons life, DNA can only be copied so many times. The only time DNA does "copy itself" would be if a new cell is needed. For example, your skin cells die all the time and are shedded off from your skins surface. Your skin then is going to get to the point where more cells are going to be made. The DNA replicating process is what starts the process of cell mitosis (making more cells). All the DNA in your body is used, so a cell does not make extra copies of DNA. If the DNA gets destroyed, that cell dies and is replaced by another.
Each cell in the human body typically contains two copies of DNA.
DNA cloning in forensic science is used to amplify and analyze DNA samples taken from crime scenes. This technique allows scientists to create copies of DNA fragments for further analysis, such as DNA profiling and identification of suspects. DNA cloning also helps in establishing genetic relationships and can be used to link suspects to crime scenes with high accuracy.

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
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
Messenger RNA (mRNA) copies DNA's instructions in the nucleus.

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.
