Why is it important that the chromosomes make exact copies of themselves before the divides?
It's because, we need to divide the cells equally with the same DNA. If chromosomes aren't copied exactly, your body parts may not be able to function the way it usually does. Sometime it could be a serious problem, otherwise, you might just get an extra toe, or something else that doesn't harm you internally.

What do chromosomes do before mitosis?
Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
Why do chromosomes line up in the middle of the cell during metaphase?
During metaphase, chromosomes line up in the middle of the cell to ensure that they are evenly distributed to the two daughter cells during cell division. This alignment helps to ensure each daughter cell receives a complete set of chromosomes. It also allows for proper segregation of genetic material.
During what phase of mitosis do chromosomes migrate to the equator of the cell and arrange themselves there?
Chromosomes migrate to the equator of the cell and arrange themselves during the metaphase stage of mitosis. This stage occurs after prophase and before anaphase, and is characterized by the alignment of chromosomes in a single plane at the center of the cell.
How do chromosomes pair up during the process of mitosis or meiosis?
During mitosis, chromosomes pair up by replicating and aligning themselves in the center of the cell before separating into two identical sets. In meiosis, chromosomes pair up in homologous pairs, exchange genetic material, and then separate into four non-identical sets of chromosomes.
Why do chromosomes in parent cell duplicate during mitosis?
Chromosomes doubles during the S phase of inter-phase, which occurs before Mitosis. During the process of mitoses cell divides into 2 daughter cells from a single parent hence, before mitoses cells must duplicate so that each new cell has a sufficient set of genetic material.
What happens to the chromosome before an animal cell divides?
The chromosomes have to split and go to opposite sides of the cell.
During binary fission of prokaryotes both the original and the duplicated chromosomes attach to what before the cell divides in half?
The original and duplicated chromosomes attach to the cell membrane or the plasma membrane before the cell divides in half during binary fission in prokaryotes. This ensures that each daughter cell receives a complete set of chromosomes.
Why does a cell make a copy of itself before it divides?
So that the new cells have the same chromosomes as the parent cells.
What do chromosomes do before mitosis?
Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
When a body cell divides through the process of mitosis what is the number of chromosomes in the daughter cells?
After mitosis each daughter cell contains 46 chromosomes as the DNA replicates itself before the cell divides
How many chromosomes are in a human cell before and after meiosis?
When meiosis begins at Gap 1 phase (G1) the cell of a human has 46 chromosomes or 2n.
Why is it important for the chomosome to make copies of themselves BEFORE mitosis occurs?
It is important for chromosomes to make copies of themselves before mitosis to ensure that each daughter cell receives a complete set of genetic information. The copied chromosomes, known as sister chromatids, are then separated during mitosis to ensure equal distribution of genetic material to the two daughter cells. This process helps maintain genetic stability and prevents loss of important genetic information.
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.
How many times do chromosomes make copies of themselves during meiosis?
Chromosomes make copies of themselves once during meiosis. This occurs during the S phase of interphase, which happens before meiosis I.
During what phase of mitosis do chromosomes migrate to the equator of the cell and arrange themselves there?
Chromosomes migrate to the equator of the cell and arrange themselves during the metaphase stage of mitosis. This stage occurs after prophase and before anaphase, and is characterized by the alignment of chromosomes in a single plane at the center of the cell.
Why do chromosomes line up in the middle of the cell during metaphase?
During metaphase, chromosomes line up in the middle of the cell to ensure that they are evenly distributed to the two daughter cells during cell division. This alignment helps to ensure each daughter cell receives a complete set of chromosomes. It also allows for proper segregation of genetic material.
Why do chromosomes need to become 2 strands before the cell divides?
The second strand of a chromosome is a copy of the genetic information for that cell. There are 2 strands so that when the cell divides, there is one copy of each chromosome for each offspring cell.
