dna vs dna chromosome
In the nucleus, the DNA double helix is packaged by special proteins (histones) to form a complex called chromatin. The chromatin undergoes further condensation to form the chromosome. So while the chromatin is a lower order of DNA organization, chromosomes are the higher order of DNA organization.
â¢ In a single cell, the number of both DNA and chromosomes are similar, but only chromosomes contain histone proteins. â¢ The DNA which is much longer (4.8 cm) than chromosomes (6 Âµm) has a less coiled structure than chromosomes.
