A duplication of the chromosomes is what must happen before meiosis can begin.

What process must occur first before any cell division take place?
Before any cell�division to occur, everything must be duplicated. That occurs during inter-phase before mitosis or meiosis begins or occurs. Fertilization -apex-
What must happen before acetyl can be formed during respiration?
Glycolysis
What cell begins meiosis and mitosis?
In meiosis, the process is initiated by germ cells (sperm and egg cells) that undergo specialized cell division to produce gametes. In mitosis, somatic cells throughout the body can undergo cell division for growth, repair, and maintenance.
When a cell undergoes meiosis one cell becomes four what also occur from meiosis?
Meiosis results in the production of four new cells, each with half the number of chromosomes as the original cell. This process introduces genetic variation by creating unique combinations of genetic material through crossing over and independent assortment. Additionally, meiosis is essential for sexual reproduction in eukaryotic organisms.

What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
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.
What k must happen before meiosis can begin?

Does DNA replication occur after telophase 1?
No, DNA replication occurs before meiosis, during the S-phase of interphase. Once meiosis begins, the DNA is already replicated, and the duplicated chromosomes are separated during meiosis I and II.
What must happen to glucose moleculs before respiration begins?
the glucose molecules must break down into two smaller molecules
What must happen before meiosis or mitosis can take place?
The cell must undergo DNA replication to ensure that each daughter cell will receive a complete set of chromosomes during meiosis or mitosis. This step is crucial for the accurate distribution of genetic material to the daughter cells.
What happens before meiosis?
Before meiosis, the cell undergoes interphase, a period of growth and DNA replication. This ensures that each chromosome has been duplicated, resulting in two identical sister chromatids held together by a centromere.
What must happen to an egg before spores are produced?
Before spores are produced, an egg (zygote) must undergo meiosis to generate haploid cells. These haploid cells can then differentiate and develop into structures that produce spores through cell division.
What must happen to the fern egg before spores are produced?
The fern egg, also known as the spore-producing structure called a sporangium, must undergo meiosis to produce spores. Meiosis is a type of cell division that results in the formation of spores with half the number of chromosomes as the parent cell.
Dolly must clean up her room before she goes out what word begins the subordinate clause?
In the sentence, "Dolly must clean up her room before she goes out," the word that begins the subordinate clause is before. The subordinate clause is "before she goes out."
Why must cells undergo meiosis before they can fuse together to produce another organism?
Meiosis produces cells with half of the DNA of a normal cell so that when two cells that have gone through meiosis (like sperm and egg) are joined, the cell formed has the normal amount of DNA. If meiosis didn't happen each new organism would have twice as much DNA as it's parents.
