Actually chromosomes are made up of single long strand of DNA wound around Histone proteins, in a specific shape.
However, CHROMATIDS(a pair of identical chromosomes) contain two strands of DNA.
prokaryotes also pack their DNA in the form of chromosomes. They lack histone protein and nuclear envelope thus their DNA is a single strand and coiled in circular shape, that is called NUCLEOID.
Hope this helped. Then do give a thumbsup! 😊👍
