yes. it has only one chromosome that holds its genetic material, however they may also have plasmids that contain genetic material

Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.
Sperm contributes one half of the genetic material,the egg supplies the other half.This is the main reason why sexual reproduction is used by most organisms. It creates diversity in species that make it more resilient to changing conditions.
A genetic disorder is something an individual is born with, and results from a problem within their genetic material. This means they have inherited the disease or disorder from their Mother or Father. You cannot inherit an infectious disease, you acquire it during your lifetime from a germ, such as a virus or a bacterium. You can also recover from an infectious disease, whereas you will always suffer from a genetic disorder if you inherit one.
the nucleus stores all the genetic information (DNA)
Bacteria are prokaryotes, which means that they do not have a nucleus (unlike eukaryotes, which do). Instead, their genetic material is contained freely in the cytoplasm of the cell; it is not bound inside a membrane.
