In the case of human chromosomes, approximately 300 G bands can usually be distinguished during metaphase. A larger number of G bands (in the range of 800) can be observed in prometaphase chromosomes because they are more extended than metaphase chromosomes.

Chromosome compaction involving progressive chromosome looping:

During prophase, condensin II binds DNA and extrudes large loops

In prometaphase, condensin I forms additional loops nested within the loops formed by condensin II
