What would happen to the chromosomes in each cell if copies of them were not made before cell division?
There would be no life
What else can I help you with?
What would happen if a cell did not make a copy of its DNA (its chromosomes) before it divided?

What is the first thing to happen in prophase in an animal cell?
The first thing to happen in prophase of animal cell division is condensation of chromatin into visible chromosomes. This process helps prepare the DNA for division by making it easier to separate and distribute to daughter cells during cell division.
What happens before cell division can happen?
the DNA makes a copy of itself
What happen to chromosomes as the zygote continues to divide?
As the zygote continues to divide through the process of mitosis, the chromosomes replicate and are evenly distributed to each daughter cell. This ensures that each new cell receives a complete set of chromosomes and genetic information. Eventually, this leads to the formation of an embryo with multiple cells containing identical copies of the original chromosomes.
What event must occur outside the nucleus before mitosis can begin?
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
What phase does the division of chromosomes happen?
Chromosomes will line up in metaphase and in anaphase they will split apart.
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
What happen during meiosis?
the process of cell division in sexually reproducing organisms that reduces the # of chromosomes in reproductive cells
What would happen if one of the chromosomes in a homologous pair fails to separate during cell division?
If one of the chromosomes in a homologous pair fails to separate during cell division, it can result in an abnormal number of chromosomes in the daughter cells. This condition, known as nondisjunction, can lead to genetic disorders such as Down syndrome.

What happen before prophase occur?
During prophase, the chromatin fibers present in the nucleus coil tightly into observable chromosomes. The centrosomes move away from each other and spindle microtubules begin to grow from them; this marks the formation of the mitotic spindle.
What would happen if there were no spindle checkpoints?
If there were no spindle checkpoints then the chromosomes wouldn't be in the right position for the reproduction of the cell.

What must happen before meiosis happen?
Before Meiosis 2, the cell must first go through Meiosis 1. This is when the cell splits into two cells, each with two chromosomes.
