each chromosome consists of two identical "sister" chromatids
The consist of DNA and various HistonesIn eukaryotes,genetic information is passed on by chromosomes. Well before cell division, each chromosome is replicated(copied). When copying occurs, each chromosome consists of two identical ''sister''chromatids.
At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
only at the time of cell division in the metaphase and in the anaphase the chromosome are visible. because at this time the chromatin get aggregate and form the thick chromosome which are visible under microscope.
At the beginning of mitosis, each chromosome is duplicated and consists of two identical sister chromatids joined together. Therefore, the number of visible chromosomes at the start of mitosis is equal to the number of unique chromosomes in the cell. This number varies depending on the organism, but for humans, there are 46 visible chromosomes at the beginning of mitosis.
During metaphase in cell division, a chromosome looks like a condensed and tightly coiled structure that is visible under a microscope. It appears as an X-shaped structure with two identical sister chromatids joined at the centromere.

two chromatids
Two chromatids are present in a chromosome at the beginning of mitosis.
The chromonemata is an individual coiled chromosome thread. The chromonemata is the coiled mass of threads visible within the nucleus at the beginning of cell division. During cell division, it remains relatively uncoiled during early prophase but assumes a more spiral shape during metaphase.
The chromosomes are located inside the nucleus of a eukaryote.
only at the time of cell division in the metaphase and in the anaphase the chromosome are visible. because at this time the chromatin get aggregate and form the thick chromosome which are visible under microscope.

During cell division, the chromatin reticulum condenses further into visible structures called chromosomes. This condensation allows for the organized distribution of genetic material to daughter cells. The chromosomes consist of DNA wrapped around protein scaffolds, which help to package and protect the genetic material during cell division.
It is made up of genes.
