DNA Replication
DNA Replication
An organisms complete set of nuclear DNA is a genome. Organism's inherit all of their mitochondrial DNA from the female parent.
AnswerThe nuclear membrane contains cell DNA and directs all cell activity.
All eukaryotes have a true nucleus with their DNA enclosed by a nuclear membrane.
In each and every cell you have, all your DNA is present as a copy. So before a cell division occurs all DNA is copied. Not all DNA information is used of course, but all is copied each and every time.

DNA replication during interphase occurs in the nucleus. All other phases of mitosis occur in the cytoplasm after the nuclear membrane is disassembled.
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?
No. Not all cells have a nucleus, which contains nuclear DNA; but all cells have mitochondria, which have their own DNA, called mitochondrial DNA, or mDNA. In humans, the cells that lack a nucleus and therefore nuclear DNA, are mature red blood cells, but they do have mitochondria and mitochondrial DNA.
DNA, nuclear membrane, and nuclear pores on the membrane
AnswerThe nuclear membrane contains cell DNA and directs all cell activity.
All eukaryotes have a true nucleus with their DNA enclosed by a nuclear membrane.
In each and every cell you have, all your DNA is present as a copy. So before a cell division occurs all DNA is copied. Not all DNA information is used of course, but all is copied each and every time.
PROPHASE
In order to give all of the daughter cells genetic material, the DNA must first be copied. Therefore DNA synthesis is essential for creating new cells.
