interphase
Telophase
Chromosones become visible during prophase.
During Prophase
chromatid
The chromosomal defect caused when part of a chromosome breaks off and reattaches backward on the same chromosome is known as an inversion. Inversions can disrupt gene function and regulation, potentially leading to various genetic disorders or developmental issues. They may not always result in visible phenotypic changes but can affect the offspring if they occur in germ cells.
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.
sperm
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.
