each chromosome consists of two identical "sister" chromatids
metaphaz. DNA and histons
When chromosomes become visible at the beginning of a cell division, each chromosome consists of two identical sister chromatids.
The chromosomes consist of pairs of sister chromatids held together by a centromere. Once the sister chromatids are separated they will be referred to as individual chromosomes.
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.
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.
Each daughter Cell has the (diploid) Chromosome Number 2N.
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.
During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye

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.
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.
interphase
Telophase
Chromosomes are the rod-shaped, filamentous bodies present in the nucleus, which become visible during cell division. They are the carriers of the gene or unit of heredity. Chromosome are not visible in active nucleus due to their high water content, but are clearly seen during cell division.
