Although rare, errors occur when cells divide and replicate, so people might have an additional chromosome attached to a pair (trisomy) or one less chromosome on a pair (monosomy). Indications are that the mitotic chromosome is formed by coiling and folding of a single DNA molecule associated with protein. A chromosome is a subpart of a persons genes while DNA is a part of the chromosome.
