polymerase chain reaction
The pattern for making proteins is determined by the sequence of nucleotides in DNA. During transcription, a segment of DNA is copied into messenger RNA (mRNA), which serves as the template for protein synthesis. The mRNA sequence is then translated into a specific sequence of amino acids, forming a protein. Thus, it is the mRNA that carries the copied genetic information from DNA to the ribosomes, where proteins are assembled.
DNA is copied
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.
DNA is copied during a process called DNA replication. This process occurs in the nucleus of a cell and involves making an exact copy of the original DNA molecule. DNA replication is essential for cell division and passing genetic information from one generation to the next.
DNA is not copied during mitosis . Mitosis is meant for division of cell and DNA is divided in two daughter cells .
antisense
In Interphase.
DNA is copied once during the process of cell division.
Polymerase chain reaction
DNA is copied in the cell nucleus. This process is called DNA replication and occurs during the S phase of the cell cycle.
