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.
When is a bacterium's circular chromosome copied?
A bacterium's circular chromosome is copied during a process called DNA replication. This typically occurs before the bacterium divides through binary fission to ensure that each daughter cell receives a complete set of genetic information.
Why must the nucleus divide before the cytoplasm?
During Mitosis, it isn't the nucleus itself that divides it is the chromatin inside the nucleus that duplicates during Prophase. This is so the new cells being created each have the correct amount of DNA for normal cell use.Because the nucleus is like the center of the cell. It tells the cell what to do and basically controls it.-6th grade science teacher
Why are chromosome called doubled chromosomes just before mitosis begins?
Just before cell division begins,the amount of DNA doubles and so do the chromosomes.Each doubled chromosome consists of two copies of the original chromosome joined at the center
How many DNA molecules are in a chromosome just before mitiosis?
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.

Before a cell divides what happens to the centrioles?
it triples in number
What happens to the info before the cell divides?
Your DNA is copied into the new cell every time it divides
What happens to the nuclear material of the parent cell before it divides?
Melios

What happens to the chromosome number during mitosis?
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
How many chromatids does each chromosome have before S-phase?
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
Are the chromosome copied before meiosis or during meiosis?
before

What is post natal development?
It is the development and growth that happens after the animal/human is born. (prenatal is before birth, postnatal is after birth)
