Telophase
Chromosones become visible during prophase.
During Prophase
chromatid
Daughter Chromosomes
I thought they were acrocentric (centromere positioned so close to the end of the chromosome that the short arm of the chromosome is not visible) rather than telocentric (centromere located completely at the terminal end of the chromosome).

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.
No, some bacteria and other unicellular organisms have a single chromosome
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.
Man is always the Y chromosome.
