Question

What advantage exists to maintaining DNA in the form of chromatin for the majority of the cell's existence?

What term describes the process by which chromatin forms chromosomes?

Thanks!

Answer 1

Chromatin is the "working" form of DNA. In order for DNA to have its genes transcribed into RNA, the DNA has to be unwound and unzipped in the area of the gene. That would be very difficult to do if the DNA were all coiled and twisted up as it is when it is in chromosome form.

Oops, I forgot the second part. This is called chromatin condensation.

Answer 2

unique mitochondrial DNA is the same old thought in the back of the mitochondrial endosymbiant thought, which says that mitochondria are derived from intercellular symbiotic prokaryotes. It explains the unique DNA, and makes some observations approximately eukaryotic evolutionary history. Prokaryotic micro organism in many circumstances carry out metabolic reactions that eukaryotes can not, so that's sensible.
