Default Does DNA make up a chromosome?

is it just one strand? I'm confused as to how a choromosome gets its X shape

not exactly...

One exists. as a direct result of the other.
I don't think that "Make up" are the right words?

a chromosome is just folded up many strands of DNA.

Actually, a chromosome is DNA plus associated proteins called "histones." DNA alone does not equal a chromosome. Also, the DNA can be tightly wound up but in some areas it may be un-wound or exposed so it can make mRNA for protein sythesis.
