DNA must be copied before cell division so that one complete copy of each chromosome ends up in each of the two daughter cells. Otherwise only one cell would end up with DNA, making the other cell.. well.. not a cell.
What else can I help you with?
What phase of the cell cycle duplicates chromosomes before division?
The phase of the cell cycle that duplicates chromosomes before division is called the S phase.
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
Why is metaphase important?
Metaphase is important because it involves chromosomes transporting genetic material to the center of a cell before becoming a couple of daughter cells. Mitosis or meiosis would be impossible without this intermediary phase.
When does the second mitotic division occur in the egg?
The second mitotic division in the egg typically occurs after fertilization by the sperm. This division takes place once the zygote has formed and involves further division of the replicated chromosomes to generate daughter cells with the full complement of chromosomes.
How are mitosis and meosis alike?
Mitosis and meiosis are both processes involved in cell division. However, mitosis results in two identical daughter cells, while meiosis results in four genetically different daughter cells. Both processes involve stages such as prophase, metaphase, anaphase, and telophase.
How many chromosomes does a human cell have before division?
64 chromosomes
What division is sexual?
It is a division that reduces the number of chromosomes to half of their number before the division.
What phase of the cell cycle duplicates chromosomes before division?
The phase of the cell cycle that duplicates chromosomes before division is called the S phase.
If the original cell has 46 chromosomes how can each daughter cell also have 46 chromosomes?
AnswerThe chromosomes replicates themselves before splitting into two daughter cells.
Why is it important that cellsDNA is duplicated before cell division?
So that each new cell has a complete set of chromosomes containing the DNA.
How many chromosomes dose a human cell have before division?
no answer
Why is it important that the cells DNA is duplicating before cell division?
So that the two new cells that are going to be made have an equal amount of chromosomes in them.
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
Why is it importaint for chromosomes to be copied before cell division?
it ensure that the cell can survive before it gets divided
Why is metaphase important?
Metaphase is important because it involves chromosomes transporting genetic material to the center of a cell before becoming a couple of daughter cells. Mitosis or meiosis would be impossible without this intermediary phase.
What is the genetic material contained in each of the 46 chromosomes of a human cell just before division?
The genetic material in each of the 46 chromosomes of a human cell just before division is DNA. DNA carries the instructions for building and maintaining an organism. During cell division, the DNA is replicated and then divided equally between the new cells.
What is a biorientation?
A biorientation is an orientation of chromosomes to opposite poles of the bipolar spindle before cell division.
