DNA Replication
Cells come from pre-existing cells through the process of cell division. Genetic information is passed on as DNA during reproduction, carrying the blueprint for life encoded in genes. Changes in the DNA sequence can result in variations and adaptations in living organisms over time through the process of evolution.
All eukaryotes have a true nucleus with their DNA enclosed by a nuclear membrane.
An organism's complete set of nuclear DNA is called its genome. This includes all the genetic material contained within the nucleus of its cells, which carries the instructions for building and functioning of the organism. Each species has a unique genome that determines its characteristics and traits.
The phase where DNA is spread out as chromatin and the nuclear membrane is visible is the interphase. This is the period when the cell is not actively dividing, but preparing for division by duplicating its DNA and organelles.

DNA Replication
Because for every cell there are many mitochondria within it so for the daughter cell to have the same amount of mitochondria all their DNA must be copied. but there is only one set of DNA within the nucleus of the cell for the cell itself so that only needs to be copied once. if that makes any sense?
DNA replication during interphase occurs in the nucleus. All other phases of mitosis occur in the cytoplasm after the nuclear membrane is disassembled.

Either the Lysogenic or the Lytic cycle. LYSOGENIC: Virus inserts DNA and the DNA goes to the nucleus and weaves itself with the DNA strand of the cell. During cell division, the virus' DNA is also copied. When a certain thing occurs to the body, such as radiation, all those cells with the virus DNA start making viruses. LYTIC: Virus inserts DNA and the DNA goes to the nucleus and weaves itself with the DNA strand. The nucleus then directs the manufacturing of many virus parts. The parts are then put together inside the cell and when there are too many viruses, the cell with explode. The new viruses that have just been made go to insert more DNA into other unfortunate cells.
(Pending a more complicated answer. :-) Exactly(?) half of your "Nuclear" DNA (DNA in the nucleus of your cells, nothing to do with nuclear energy!) is identical(?) to your mother's. All(?) of your "Mitochondrial" DNA (DNA in your "Mitochondria") is identical(?) to your mother's. (Two reasons for the the question marks would be mutations and transcription errors.) See the links.
In the nuclear DNA both parents contribute equally. However the mother contributes all of the mitochondrial DNA. Blood types are determined entirely by the nuclear DNA, so both parents contribute equally.
