They are copies because so that new cells have the same chromosomes as their parent cells.Because each daughter cell needs its own set.
the parts of the cell which are copied during cell division are chromosomes.
I think that because you when you copy something you are making an exact replica of it.
Chromosomes are invisible except during cell division because the DNA stays in the nucleus. This is to protect it.
yes
The chromosomes are attached to different parts of cell membrane, which elongates and thus separates the chromosomes
the parts of the cell which are copied during cell division are chromosomes.
To make all cells identical.
I think that because you when you copy something you are making an exact replica of it.
it ensure that the cell can survive before it gets divided
During cell division.
Chromosomes are copied during S phase, before cell division begins. This is so that each daughter cell receives the right amount of genetic material. In mitosis, the daughter cells receive the same number of chromosomes as in the original cell, in meiosis they receive half of this.
During cell division the chromosomes are copied and they form sister chromatids. Then the mitotic spindle attaches to the sister chromatids and pulls them apart, splitting the nucleus in two. Then the cell goes through cytokenesis and the cell membrane is pinched together in the center, this divides the organelles and the cytoplasm between the two daughter cells.
Chromosomes replicate during cell division, so are present as a new cell forms.
