The information of the human genome is encoded by approximately 3 billion DNA base pairs and packaged into 23 pairs of chromosomes.

The information of the human genome is encoded by approximately 3 billion DNA base pairs and packaged into 23 pairs of chromosomes. If all chromosomes could be disentangled and linearly aligned, they would be a thin thread of about 2 meters. The DNA molecule must be extensively packaged to fit inside the nucleus, the size of which is in the micrometer range.
The DNA thread is not simply stuffed into the cell nucleus. Instead, it is folded in a very organized way to ensure that different parts of…
