X chromosome only
Bacteria typically have a single, circular chromosome that is not contained within a nucleus. This chromosome carries the majority of the bacterium's genetic material and is essential for the organism's survival and reproduction.

Tay-Sachs disease is caused by mutations in the HEXA gene located on chromosome 15. These mutations result in the absence or deficiency of the enzyme hexosaminidase A, leading to the accumulation of harmful substances in the brain and nervous system.
Chromatin loops and nucleosomes are useful structures within a chromosome as they help to store genetic information. This allows for complex codes to be contained within chromosomes.
They are located within the Chromosome: freely floating in Prokaryotes; contained within the nuclear envelope in Eukaryotes.
These atoms decide the chemical composition of the substance.
The replicated DNA of each individual chromosome is contained within sister chromatids, which are identical copies of a chromosome formed during DNA replication. Each chromosome consists of two sister chromatids joined together at a region called the centromere. During cell division, these sister chromatids are separated to ensure that each daughter cell receives an identical set of chromosomes.
Chromosomes are the same no matter what gender you are, or what species, all cells have them. It is the information contained within those chromosomes that is different between cells.
