The length of the DNA strands on the gel can be determined by comparing their migration distance to a DNA ladder or marker of known sizes. Typically, the strands can range from a few hundred base pairs to several thousand base pairs in length, depending on the specific DNA fragments amplified or isolated. By measuring the distance traveled by the DNA bands and referencing the ladder, we can estimate the size of the strands accurately.

It is called DNA supercoiling. This coiling helps to compact the long strands of DNA into the small space inside a cell.
DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
When DNA is in long strands, it typically forms chromatin structures by wrapping around histone proteins to condense into nucleosomes. This packaging allows for the long DNA strands to be compacted within the nucleus of a cell. Additionally, the chromatin structure can undergo further condensation to form chromosomes during cell division.
DNA is found inside prokaryotic cells freely floating in the cytoplasm. It is in long strands bundled in the cell.

A DNA molecule typically consists of two strands.
There is no such thing called a DNA nucleus. I assume you mean DNA found in the nucleus. The DNA that's found in the nucleus are many DNA strands all bunched up.
Short strands of DNA move more quickly than long strands because they are smaller and can navigate through obstacles more easily.
Chromatin occurs as long thin strands of DNA. They are found in a loosely packed formation. While chromosomes are formed by a tighter packing, via coiling and compact folding of the DNA protein complex are thus visible.
