Chromosomes are copied during S phase, before cell division begins. This is so that each daughter cell receives the right amount of genetic material. In mitosis, the daughter cells receive the same number of chromosomes as in the original cell, in meiosis they receive half of this.

What is meiosisI?
Meiosis is the type of cell division that results in gametes (sex cells) that possess half the chromosome number of the parent cell. In other words, meiosis reduces the chromosome number by one-half.
What cell division make gametes?
A special cell division called meiosis produces gametes(sex cells).
What happens to the cell during the mitosis phase?
Protein spindles form on the centrioles which move to opposite poles in the Cell. These spindles attach themselves to one side on the chromosome with extreme precision and the spindles on the opposite centriole, attaches itself to the other half. The chromosomes are brought to the centre of the Cell. Hence, the chromosomes are split into two.
Smallest to largest cell nucleotide nucleus DNA chromosome?
Cell, nucleus, chromosome, DNA, nucleotide.
What do a cells chromosomes contain?
If we use the word "chromatid", there are always two. (As with twins!)In a eukaryotic cell immediately after cell division (mitosis or meiosis), each chromosome contains only one DNA molecule.If the cell is preparing for a subsequent division, then midway through interphase the DNA replicates. Now there are two molecules of DNA in each chromosome.At the start of the following division, in prophase, the chromosomes condense, and the two DNA molecules, with their many associated proteins, become visible under a light microscope as sister-chromatids.
What make possible the precise separation of DNA during cell division?
Chromosome make possible the precise separation of DNA during cell division
How can one cell make copies of itself?
Cell Division or Mitosis
What is the process of which cells can make copies of itself?
Cell division.
Describe the chromatids that make up a chromosome when a cell is ready to divide.?
Describe the chromatic that make up a chromosome when a cell is ready to split
What is the difference between cromatin reticulam and cromosome?
Chromatin refers to the combination of DNA and proteins that make up the genetic material in the cell nucleus. It is a loosely organized structure. Chromosome, on the other hand, is a condensed and tightly coiled structure formed by the packaging of chromatin during cell division. Chromosomes are visible under a microscope and are essential for cell division and the transmission of genetic information.
What is chromatid?
* the two exact copies of DNA that make up each chromosome.
What is meiosisI?
Meiosis is the type of cell division that results in gametes (sex cells) that possess half the chromosome number of the parent cell. In other words, meiosis reduces the chromosome number by one-half.
Describe the chromatids that make up a chromosome when a cell is ready to divide?

Why do they have identical chromosome?
Since we all come from a single cell that's multiplied billions pf times to make us - each cell is an exact copy of itself - therefore the chromosomes are identical.
What cell division makes new cells?
Every cell division make new cells.Mitosis make diploid cells.Meiosis make haploid cells.
Difference between nuclear division and cell division?
Cell division is when a cell splits in two to make more cells, and the cycle is where the cell does all the other stuff. A full life span of a cell is cell cycle that include cell division+ cell death and cell division cycle is the process of a cell to divide into two.
What cell make the molecules and organelles needed for cell division?
G2
