What is the packing ratio of a chromosome and what is its range in a single chromosome?

What will be an ideal response?


Ans: The packing ratio is a measure of the compactness of a chromosome, calculated as the length of DNA (in base pairs) divided by the length of the chromosome (in ?m) at a given time. The maximum packing ratio of a eukaryotic chromosome, which occurs during mitosis, is about 7000; during interphase, typical packing ratios are about 1000 to 2000.
